Research of a Small-Scale Building Integrated Photovoltaic Micro-Grid System

摘要

The paper presents the design of a small-scale building integrated photovoltaic micro-grid system, which is a master-slave system with bi-directional battery inverter as the core of the system.A photovoltaic energy system and management system are established, which has the function of real-time data monitoring and logging, switches different micro-grid operation mode. On this basis, the photovoltaic cooling water system is presented to solve the decline in peak power generation of the system caused by the increase of the temperature of the photovoltaic panel. Experimental results show that the stability of the system can run in networked mode and island mode, cooling water system of photovoltaic panels improve the total system power generation.
