基于动态运行策略的混合能源微网规划方法

摘要

A system planning model is proposed considering the operation strategy constraint of hybrid energy microgrid.A hybrid energy system model is established including solar power,wind power,micro-turbine and energy storages.Taking the minimum annual net cash flows as the target,an example analysis is used to design a smart park hybrid energy system,and a variable step space search process is used to achieve the best distributed power unit capacity.According to the optimal result,the system energy balance relationship in different seasons and times is analyzed,and the influence of time of use power price on the microgrid operation is discussed.%在考虑混合能源微网动态运行策略约束的同时,提出了建立系统规划模型的方法,并建立了包含光伏发电、风力发电、微型燃气轮机热电联供和储能的混合能源微网规划模型。以年现金流最小为优化目标,结合算例分析对某办公园区混合能源微网系统进行了规划设计,采用变步长空间搜索方法计算得出最佳分布式发电单元容量,分析了算例系统在不同季节和时刻的能量平衡关系,讨论了分时电价对混合能源微网系统运行的影响。
