摘要(Abstract):
近年来我国智能化小微园区建设规模迅速增长,如何在最大化利用能源的情况下保证经济效益是当前面临的重要问题。针对小微园区能量优化问题,建立了基于小微企业需求响应的光-储并网微电网优化模型。该模型在分析负荷特性的基础上,结合分时电价与光伏系统出力信息引导小微企业参与需求响应,同时考虑在光-储并网条件下,基于分时电价采取谷时储能、峰时释能的运行策略,优化园区能源调度,实现日前24 h园区经济运行成本最低的目标。仿真结果表明:以经济性为目标的能量优化模型,优化管理各系统之间的能量交互,可有效控制园区的经济运行成本。
The intelligent micro and small industrial parks scale up in China in recent years, and it is a key issue to maintain economic benefits and in the meantime to ensure maximum energy utilization. Therefore,this paper establishes an optimization model of the photovoltaic-storage grid-connected microgrid system based on the demand response of small and micro-enterprises. This model guides the micro-enterprises to participate in the demand response by analyzing the load characteristics of the micro-enterprises and combining the information of the time-sharing electricity price and the photovoltaic system output; meanwhile, it achieves the goal of minimum cost of all-day economic operation given photovoltaic-storage integration based on valley load energy storage and peak load release of time-sharing price to achieve a minimum cost of all-day operation.The simulation results show that the energy optimization model with the aim of economic operation enables optimal management of energy interaction between all systems and can effectively manage the cost of economic operation in the parks.
