Published: May 4, 2025

In distribution networks with high penetration of distributed generators (DGs), traditional fault reconfiguration strategies often fail to achieve maximum load recovery and encounter operational stability challenges. This paper proposes a novel two-stage strategy that addresses both the ride-through capability output uncertainty DGs. The first stage introduces rapid power restoration model integrates network ride-through, enabling DGs provide support during faults, thereby significantly improving rate lost loads. An AdaBoost-enhanced decision tree algorithm is utilized accelerate computational process. second post-recovery optimal uses fuzzy mathematics theory transformation chance constraints quantify generation load, system’s static voltage index. Case studies using IEEE 69-bus system real-world validate effectiveness proposed strategy. facilitates short-term enhances long-term stability, resilience reliability DG penetration. findings this research contribute enhancing tolerance efficiency modern systems, which essential for integrating higher levels renewable energy.

Owing to the intermittent nature of renewable energy, complexity battery systems, and various factors affecting investment decisions, comparison between non-renewable energy systems is challenging. This study addresses multi-target problem local comprising photovoltaics, wind turbines, batteries, a power grid connection for industrial small- medium-sized enterprises. The applied multi-objective analysis considers four dimensions (self-sufficiency, costs, lifecycle emissions, land consumption) optimize combination components system describe trade-offs. extends prior research, which primarily focused on cost parameters residential applications. Our findings are Pareto fronts optimized combinations electricity procurement or sale. Using manufacturing facility in Germany with 5 GWh consumption test model, results show that such site fully powered by approximately 22 % more expensive than conventional case. However, implementing company's an extent 60–70 its can reduce costs emissions up 27 60 %, respectively. If excess fed directly into at high price, advantage be generated. Overall, suggest these objective should considered simultaneously guide decisions.

A Cooperative Operation Strategy for Multi-Energy Systems Based on the Power Dispatch Meta-Universe Platform

Electronics, Journal Year: 2024, Volume and Issue: 13(15), P. 3015 - 3015

Published: July 31, 2024

To meet the challenges of renewable energy consumption and improve efficiency systems, we propose an intelligent distributed dispatch strategy for multi-energy systems based on Nash bargaining by utilizing power meta-universe platform. First, operational framework system, including wind park (WP), photovoltaic plant (PVPP), storage (ES), is described. Using platform, models WP, PVPP, ES are constructed analyzed. Then, a model system built transformed into coalition profit maximization problem, which solved using alternating direction multiplier method (ADMM). Finally, effectiveness proposed verified. The results show that greatly improves sources overall system.
