Energy systems optimization modelling can be applied to evaluate policy scenarios in the power sector to accelerate energy transitions. These modelling tools need data to simulate different scenarios in the power system to clarify the design of energy policies. For this reason, collecting and processing technical and economic data is needed to guarantee quality input for the modelling tools. This article presents a dataset for an optimization model of the generation mix and the energy demand in the power system of the Dominican Republic to determine the capacity value of variable renewable energy (VRE), i.e., wind and solar, that can serve as an incentive for these technologies. While the data corresponds to the Dominican Republic's power system, the method of collecting and processing data can be implemented in other countries. The data collected is an open-access database of the independent system operator, the power sector regulator, and utilities, as well as websites and databases of international organizations.

This study introduces a new approach to assessing the Economic Capacity Value (ECV) of VRE resources, which measures their contribution to system reliability, considering resource availability and market conditions. The methodology is applied using a co-optimization model of the energy market and the capacity remuneration mechanism that minimizes total system costs and capacity payments. The framework is applied to the Dominican Republic's electricity market, using 2023 demand and generation data. Results show that VRE resources provide a significant contribution to system reliability under existing market conditions. Solar photovoltaic ECVs range from 21.8 MW (17.2%) in the north region to 107.2 MW (33.6%) in the southwest, while wind power exhibits higher values, reaching 87.6 MW (43.9%) in the north and 74.7 MW (34.4%) in the southwest. In all cases, ECV surpasses the capacity factor, indicating that VRE contributes more to reliability than its average production suggests. Sensitivity analysis shows that ECV is highly sensitive to market design parameters, with ±25% variations in capacity payments or scarcity prices resulting in ECV changes of up to 34%. These findings show that capacity value can be influenced by both resource availability during high demand periods and market design, supporting the inclusion of VRE in capacity remuneration mechanisms based on ECV. • A novel methodology is proposed to estimate the Economic Capacity Value (ECV) of VRE power plants. • A co-optimization model of the energy market and the capacity payments is built for the application of the methodology. • A case study estimates regional ECV of VRE in north, southwest, and southeast regions of the Dominican Republic for Citas OpenAlex: 0 | Cuartil SJR: Q1 variable renewable energy capacity remuneration electricity market design system reliability capacity payments wind energy photovoltaics capacity factor Energy Reports 2352-4847 vol. 15, p. 109300-109300, (2026) doi:10.1016/j.egyr.2026.109300 https://doi.org/10.1016/j.egyr.2026.109300 Texto completo vía DOI Versión publicada https://doi.org/10.1016/j.egyr.2026.109300 Acceso abierto ART 00000nab a2200000 4500 10.1016_j.egyr.2026.109658 OREX-CRIS 261111s2026 sp o 000 0 eng d m o h cr ||||||||||| 2352-4847 10.1016/j.egyr.2026.109658 doi OREX-CRIS spa rda OREX-CRIS eng Aybar-Mejía, Miguel, autor aut (orcid)0000-0002-4715-3499 Rivas-Peña, Yeulis V., autor aut (orcid)0009-0002-3868-9555 Ocaña-Guevara, Víctor S., autor aut (orcid)0000-0003-3794-2336 Uceta-Acosta, Rafael O., autor aut (orcid)0009-0005-7562-7224 Henriques-Dias, Bruno, autor aut (orcid)0000-0002-7663-235X Domínguez-Garabitos, Máximo A., autor aut (orcid)0000-0001-6948-7337 Operating reserve allocation in the Caribbean small island electricity market with high shared variable renewable energy: A review and methodological framework Miguel Aybar-Mejía; Yeulis V.

This paper presents a systematic literature review of regulatory frameworks, electricity market structures, and optimization approaches for operating reserve allocation across the 15 United Nations-affiliated Caribbean SIDS. A comparative assessment is performed to evaluate the applicability of existing optimization methodologies to the operational characteristics of Caribbean SIDS. The review identifies Mixed-Integer Linear Programming (MILP) as the most suitable computational foundation for reserve allocation, while highlighting the complementary roles of robust and stochastic optimization under different levels of uncertainty and data availability. The analysis further reveals five key research gaps, including the absence of integrated methodological frameworks adapted to the regulatory, operational, and institutional characteristics of Caribbean SIDS. To address these gaps, a PDCA-based continuous improvement framework is proposed, providing a structured and adaptable methodology to support reliable reserve allocation, facilitate higher VRE integration, and promote sustainable electricity market development in isolated island power systems.

The electricity industry must gain operational flexibility to support the energy transition caused by renewable energy and decarbonization. Complementary services and technologies of demand response programs can be optimized by exploiting the variety of uses of this resource. The main objective of this work is to apply the concept of elasticity of substitution in a strategic demand shift program to promote the integration of renewable energies and the reduction of non-served power, considering an economical and safe generation dispatch. The methodology is analyzed through a case study applied in the Dominican Republic’s electricity market, in which the elasticity of substitution coefficients is used to adjust variations below 10.49% of the base demand in the peak period. These variations reduce the generation operating cost by 8.4%, marginal cost by 30.19%, and non-served power by 19.1% when renewable energy increases by 5%. The inclusion of the cost of CO2emissions in the simulation of the operating cost function makes the objective function higher than the baseline function. For relative variations in operating cost ranging from 7.27% to 16.03%, the reduction in tons of CO2equivalent varies from 2.77 to 28.02. This study contextualizes the economic effect of the CO2emissions control, giving new possibilities to optimize system operation and the wholesale electricity market based on demand response programs that encourage flexible consumption, with favorable economic and environmental results.

Fuentes: openalex, orcid Acceso restringido In the electricity system, the frequency behavior is an indicator of the quality of the service provider that expresses the equilibrium between the supply and demand of electricity. Demand presents challenging to predict behavior, which means that usually, the balance is corrected through changes in a generation. The operators rely on generation plants that must keep 3% of their power available for regulation. With the increase in electric vehicles (EV) and the growing vehicle-to-grid (V2G) technology, the frequency regulation service could be supplemented and mitigated by generators. This research aims to analyze the viability and feasibility of the use of V2G technology as a complementary service to primary frequency regulation. The battery model of electric vehicles with the necessary components for its operation in V2G was simulated using the PowerFactory DIgSILENT software. A single bank with all the power connected to a system Monte Carlo simulation of a single bank was carried out with all the power connected to a system bus to simulate the entire fleet of electric vehicle batteries and know how much power was always available. The results obtained in the simulations show that theso of the EVs in the primary frequency regulation does not allow sudden changes in frequency in the electrical system.

This study investigates how electric mining vehicles with vehicle-to-grid (V2G) technology can be integrated into power grids to improve system stability and frequency regulation. In the context of mining operations and the provision of auxiliary services (such as primary frequency regulation) to an interconnected electrical system, a regulatory framework that enables V2G integration should be established. This issue is addressed through a case study involving DIgSILENT PowerFactory simulations. The goal is to evaluate the productive process of a mine and the contribution of V2G technology to the primary frequency regulation of the electrical system under different scooptram integration parameters and battery electric trucks. This study also explores the challenges of V2G implementation in the absence of a regulatory framework. Different configurations of electric scooptrams and shovel that can affect frequency regulation are assessed. The obtained optimal configuration involves two truck loaders and three shovel loaders; the capacity of the current electrical infrastructure can support this configuration without affecting the capacity of the mine's electrical system. The simulations verify that applying V2G technology to mining vehicles helps stabilise the frequency of electrical systems and reduces the probability of component failure.

Distributed Generation (DG), particularly solar photovoltaics, has become a key component of modern power systems, especially in distribution networks. However, its increasing penetration at both utility and distributed levels poses challenges related to voltage, frequency, and angular stability, requiring advanced monitoring and control strategies. In this context, energy storage systems (ESS) emerge as a crucial player, playing a significant role in mitigating these challenges. ESS stabilizes power supply fluctuations and enhances grid reliability, providing a safety net for the intermittent nature of renewable energy sources. This study examines the impact of DG on the stability and operation of the National Interconnected Electric System (SENI) of the Dominican Republic, with a focus on integrating ESS at both utility and distribution levels. Using DIgSILENT, future scenarios (2027) with high renewable penetration were simulated. The methodology included data collection, modeling of actual automatic load shedding (EDAC) events from 2024, and the simulation of three scenarios: without storage, with utility-scale storage, and with both utility-scale and distributed storage. The results indicate that energy storage systems (ESS) significantly enhance system stability, reducing both the total disconnected load and the number of EDAC steps. In the absence of storage, 640 MW were disconnected; with utility-scale storage, this was reduced to 540 MW, and the addition of distributed storage further decreased the disconnected load to 440 MW while also delaying EDAC activation times.

Existing reserve sizing practices typically rely on either fixed deterministic rules or data-intensive probabilistic methods, both presenting practical limitations in Small Island Developing States (SIDS). This paper develops a market-based framework for the co-optimization of energy and operating reserves in low-inertia island power systems, in which reserve requirements are determined from historically observed extreme generation or load deviations that represent operationally validated high-risk system conditions, while reserve allocation and pricing emerge from the co-optimization process. By relying on observed operational variability, the proposed approach avoids explicit probabilistic uncertainty modeling while retaining sensitivity to system stress conditions. The approach is evaluated using a stylized island power system representative of Caribbean SIDS. Results show that reserve requirements are highly sensitive to operating conditions, reaching up to 26.7% of demand under high variability and significantly exceeding conventional fixed reserve criteria. The framework reduces non-served energy, improves reserve allocation efficiency, and generates scarcity-consistent reserve prices under stressed conditions. These findings demonstrate that the proposed methodology provides a practical intermediate solution between deterministic and probabilistic reserve sizing approaches while remaining suitable for data-constrained island power systems.

Fuentes: openalex, orcid, sjr Acceso abierto — GOLD The energy transition has shown that fossil generation can be complemented with renewable energy and other resources capable of providing flexibility to the energy system’s operation, in compliance with the wholesale electricity market’s rules. This paper proposes a market-based methodology for introducing flexible demand in the energy dispatch, optimizing the scheduling of electricity system operation in the short-term, and considers the challenge of implementing an incentive scheme for participants in demand-response programs. The scheme includes the criteria of the elasticity of substitution and a renewable energy quota. This methodology is focused on a strategic demand shift to minimize the cost of supply; increase the dispatch of renewable energy; control CO2 emissions; and satisfy the generation, demand, and transmission operating constraints. These conditions encourage the development of a simulation tool that allows a sensitivity analysis to aid decision-making by operators and agents. The proposed methodology optimizes the operational cost of generation supply and specific performance indicators to determine the percentages of demand shift, the amount of CO2 emissions, the ratio of unserved power, the demand benefits obtained from an incentive scheme, and the natural market behavior.

The Eastern, Northeastern, and Southern regions were identified as the areas with the most significant potential for energy generation. This potential can be harnessed to complement intermittent or unmanageable renewable energies in distributed generation networks. Biomass generation plants can be hybridized with other sources, such as wind and solar, to provide a more stable and reliable electricity supply. The methodology developed to evaluate the energy potential of residual biomass in the Dominican Republic integrates a rigorous review of the literature and agricultural databases, incorporating criteria such as annual production, residue-to-product ratio, higher calorific value, and dry matter content, culminating in a formula that synthesizes normalized data to optimize the selection and projection of biomass sources based on their potential energy contribution. The study found that the Dominican Republic has significant potential for energy generation from residual biomass, which can be leveraged to provide a more stable and reliable electricity supply.

Fuentes: koha Acceso restringido Los sistemas eléctricos de potencia enfrentan desafíos que exigen de una adecuada planificación de la operación para satisfacer los requerimientos energéticos de la demanda en un mercado eléctrico mayorista, debido a la dependencia de los combustibles fósiles, la volatilidad de los precios del petróleo, y la incertidumbre en la oferta de generación, especialmente de las renovables variables que han servicio de soporte para impulsar el cambio climático desde este sector. Con el desarrollo de nuevas tecnologías y mecanismos de innovación metodológica, la transición energética ha demostrado que la generación fósil y la alta penetración de renovables variables pueden coexistir con programas de respuesta de la demanda capaces de aportar flexibilidad a la operación segura del sistema, cumpliendo las reglas del mercado eléctrico mayorista y los criterios de descarbonización. El objetivo de esta investigación se concentra en la estrategia de desplazar demanda a partir del concepto de elasticidad de sustitución, en un modelo de optimización que minimiza el costo de suministro y maximiza los incentivos de los usuarios participantes, aumentando el despacho de energía renovable variable y reduciendo las emisiones de CO2. La modelación se puede ajustar para priorizar otros usos, como la mitigación de la potencia no servida y las congestiones de red. Los resultados de la metodología se analizaron por medio de un caso de estudio aplicado en el mercado eléctrico mayorista de la República Dominicana, en el que se utilizó la elasticidad de sustitución para ajustar desplazamientos de demanda de la línea base durante el periodo de punta por debajo del 10.49%. Esta variación motivó una reducción del costo de explotación de la generación en 8.4%, del costo marginal en 30.19% y de la potencia no servida en 19.1%, cuando la energía renovable aumentó en 5%. Un incremento del costo de las emisiones en 10 US$/ton, representó una variación relativa del costo de explotación desde 7.27% hasta 16 Energía eléctrica Demanda de energía eléctrica Recursos energéticos renovables Política energética BK
