摘要
合理规划分布式光伏与储能系统之间的资源配置关系可为电网提供长期、持续和稳定的电源支撑.基于居民户用分布式光伏储能系统,参考光伏发电的平准化度电成本模型,加入储能电池的度电成本函数,考虑电池充放电时电网的实时电价以及储能电池的充放电成本进行资源优化配置.结果表明:资源优化能够有效降低系统的使用成本;光伏发电和储能电池的加入能够明显提高微电网系统的独立性和稳定性,并大大增强了微电网系统抵抗恶劣天气和电网突发情况的能力.
Abstract
Rational planning of the resource allocation relationship between distributed photovoltaic and energy storage system can provide long-term,continuous and stable power support for the power grid.Based on the distributed photovoltaic energy storage system for residential use,the kilowatt-hour cost function of the energy storage battery was added referring to the levelized kilowatt-hour cost model of photovoltaic power generation,and the real-time electricity price of the grid and the charge and discharge cost of the energy storage battery were considered to optimize the resource allocation.The results show that resource optimization can effectively reduce the use cost of the system;the addition of photovoltaic power generation and energy storage batteries can significantly improve the independence and stability of the microgrid system,and greatly enhance the ability of the microgrid system to resist bad weather and power grid emergencies.
