摘要
在电网有充电限制的条件下,根据“光伏+储能”系统需在每天固定时间段内恒定输出功率的要求,提出了一种通过综合考虑“光伏+储能”系统平准化度电成本和净现值收益率来分步确定此类系统最大恒输出功率及储能容量的方法,并以某项目为例,利用MATLAB软件进行了模拟仿真验证。仿真结果表明:所述计算方法有效解决了微电网恒输出功率要求下储能设备容量选择问题。该方法可作为解决同类型问题的参考。
Under the condition of charging restrictions in the power grid,this paper proposes a method to determine the maximum constant output power and energy storage capacity of a“PV+energy storage”system step by step by taking into account the LCOE and net present value rate of return of the“PV+energy storage”system,based on the requirement of constant output power for afixed time period every day.Taking a certain project as an example,simulation verification was conducted using MATLAB software.The simulation results show that the calculation method described in this article effectively solves the problem of selecting the capacity of energy storage equipment under the constant output power requirement of the micro-grid.This method can serve as a reference for solving similar problems.
