However, integrating renewable energy sources, managing fluctuating load demands, and addressing uncertainties in electricity prices introduce significant challenges in maintaining system resilience. This paper introduces a novel probabilistic scheduling framework for simultaneous unit commitment and network reconfiguration, integrating renewable energy sources, energy storage systems, and demand response programs into a unified optimization model. The framework explicitly addresses uncertainties related to renewable generation, load demand, and electricity prices, ensuring robust decision-making under real-world conditions. Additionally, the model incorporates emergency load curtailment contracts and adaptive load shedding to enhance resilience during critical conditions. The microgrid under study comprises wind turbines, micro-turbines, and battery storage systems, serving both critical and non-critical loads. The pelican optimization algorithm is employed as a solution tool to solve the optimization problem efficiently. Simulation results demonstrate significant improvements in microgrid performance, stability, and resilience, particularly under extreme conditions. By addressing critical research gaps in the integration of unit commitment, reconfiguration, and demand response, this study provides a comprehensive and adaptive solution for optimizing microgrid operations. The findings offer valuable insights for energy system planners and policymakers aiming to develop resilient and sustainable energy infrastructures.</div></div>","PeriodicalId":50326,"journal":{"name":"International Journal of Electrical Power & Energy Systems","volume":"168 ","pages":"Article 110710"},"PeriodicalIF":5.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a new passive (P) technique using Cex (external parallel capacitor) is proposed and its performance is compared with the methods using Rex (parallel resistor), MOA (metal oxide arrester), Cn (grounding capacitance), Rn (grounding resistance), and Rcb (parallel to CB resistor) components. The mathematical models of the approaches are derived and their bifurcation diagrams for the peak voltage versus the method parameter are computed. The results indicate that the Rex, Rn, Cn, and Cex designs can effectively suppress the ferroresonance and limit the peak voltage to less than safe 2pu. However, since the Rex, Rn, and Cn methods disrupt the PT’s normal operation, those cannot be installed permanently and must be triggered by a ferroresonance detection module (FDM). Besides, the heat generated by the Rex and Rn methods is considered another disadvantage. As a result, the proposed Cex method with no heat generation, availability at power stations and not requiring FDM viewed as a prime choice.

In order to optimize the layout and capacity of APF connected to the grid, this paper proposes a hybrid Improved algorithm for the economic optimization of APF configurations. Initially, based on Beluga Whale Optimization, a multi-strategy Improved algorithm is introduced, and through verification on benchmark test functions, this method effectively improves convergence speed and accuracy. Subsequently, to achieve economically optimal conditions while meeting IEEE 519 standards, IBWO is employed to search for the installation positions and capacities of APF. Through practical validation, the Total Harmonic Distortion (THD) of each bus before APF installation exceeds 5%, and after optimization configuration, the THD of each bus falls below 5%. This significantly reduces grid distortion, meeting the standards for grid operation.

This paper proposes a simulation-based online dynamic programming approach to provide real-time restoration actions considering the dispatch of mobile resources. Using an index-based priority rule as the base policy, the remaining cumulative loss at the current state and a given action is evaluated from online simulation. As the base policy is explicit, the simulation is efficient. Then, the action leading to the minimum cumulative loss is chosen. It is proven that such a strategy improves the performance of base policy. The proposed policy adapts to real-time information updates and does not rely on offline training, so incurs no data and convergence-related issues, which is important in restoration tasks where the historical data of extreme events is rare. The rolling optimization approach may not meet the requirement of online use, because routing mobile resources gives rise to large-scale discrete optimization problems.
