【摘要】：为了稳定并网型微电网输出功率,需要平滑并网型微电网的输出功率曲线。含多类储能的并网型微电网因其储能形式的多样化,在应对各种恶劣的条件下亦能稳定地输出功率,保证敏感负荷供电,因而对含多类储能的并网型微电网的优化运行研究日渐成为热点。微电网优化运行需要根据微电网的特性研究具有针对性地优化运行控制策略,并且尽可能多地利用新能源。目前,国外对于含多类储能微电网优化运行理论的研究较多,而国内还处于起步阶段。基于一个含多类储能的微电网项目,在现有实验数据基础上,设计了一种并网运行模式下的优化控制方案。结合储能的实时状态和实时电价,对含多类储能的并网型微电网能量优化提出了一套经济的解决方案。仿真分析表明,该优化控制方案可实现良好的经济效益。
[Abstract]:In order to stabilize the output power of grid-connected microgrid, it is necessary to smooth the output power curve of grid-connected microgrid. Because of the diversity of energy storage forms, grid-connected microgrids with multiple types of energy storage can steadily output power under various adverse conditions and ensure the supply of power to sensitive loads. Therefore, the research on optimal operation of grid-connected microgrid with multiple types of energy storage has become a hot spot day by day. According to the characteristics of microgrid, the optimal operation control strategy of microgrid needs to be studied, and the new energy sources should be used as much as possible. At present, there are many researches on optimal operation theory of microgrid with multiple types of energy storage in foreign countries, but in China, it is still in its infancy. Based on a microgrid project with multiple types of energy storage, an optimal control scheme in grid-connected operation mode is designed on the basis of existing experimental data. Based on the real time state of energy storage and the real time electricity price, a set of economic solution for energy optimization of grid-connected microgrid with multiple types of energy storage is proposed. Simulation results show that the optimal control scheme can achieve good economic benefits.
