摘要/Abstract

摘要： 微电网容量配置研究的目的是在保证供电可靠性的同时,降低微电网系统的成本。借鉴现有分布式电源、储能和微电网的研究和运行经验,提出了一种微电网容量优化配置方法并开发了一套微电网规划设计软件。对于并网型微电网容量优化配置模型,综合考虑了输送功率、短路电流比、电压损耗、电压波动的系统约束,优化了遗传算法的搜索空间,保证了结果的合理性。针对孤岛型微电网和并网型微电网,制定了不同的能量控制策略,提高了算法的通用性。通过对江苏某微电网示范项目的规划设计,验证了方法的可行性和有效性。

Abstract: The purpose of microgrid capacity configuration is to reduce operation cost while ensuring power supply reliability. With consideration of existing research and operating experience on DG(distributed generation), energy storage and microgrid, an optimal capacity configuration method is proposed, and a software DGPO(distributed generation planning and optimization) is developed. During optimization of grid-connected microgrid, constraints including transmission power, short-circuit current, voltage loss, voltage fluctuation are considered. Search space of genetic algorithm is optimized to ensure rationality of results. Different energy control strategies are formulated to improve algorithm generality for both isolated-island and grid-connected microgrid. The feasibility and effectiveness of proposed method is verified through a microgrid demonstration project in Jiangsu.

Key words: microgrid, distributed generation, energy storage, control strategy, capacity configuration
