Abstract

Goal of this paper is to provide performance analysis of photovoltaic based microgrid (PVMG). This is accomplished with energy management system (EMS) developed as Mixed Integer Linear Programming (MILP) problem evaluated on different case studies. Studied microgrid (MG) consists of PV system, load and battery storage system (BSS). Developed algorithm optimizes electricity flow in the MG by managing operational points of elements with the final goal of serving electricity demand at the lowest expense. Performance analysis of PVMG operation is performed for three study cases - passive consumer, prosumer and PVMG. Input data for the case studies represent 7 days of measurements of solar irradiance and ambient temperature for European humid-continental climate while load represents measurements of household electricity consumption in South-eastern Europe. Finally, sensitivity analysis of the impact of PV system array size and BSS capacity on operational profit of the PVMG operator (owner) for the scheduling horizon is carried out.

简易光伏微网能源管理系统性能评价

本文的目的是对光伏微电网(PVMG)进行性能分析。这是通过能源管理系统(EMS)开发的混合整数线性规划(MILP)问题来完成的，并通过不同的案例研究进行了评估。所研究的微电网由光伏系统、负载系统和电池储能系统组成。本文提出的算法通过管理各要素的运行点，以以最低的费用满足电力需求为最终目标，对电网中的电流流进行优化。对被动消费者、产消者和PVMG三个研究案例进行了PVMG运营绩效分析。案例研究的输入数据代表了欧洲湿润大陆气候下7天的太阳辐照度和环境温度测量值，而负荷代表了东南欧家庭用电量的测量值。最后，对PV系统阵列规模和BSS容量对PVMG运营商(业主)运营利润的影响进行了调度水平的敏感性分析。
