Management of renewable energy source and battery bank for power losses optimization

Abstract

Abstract This chapter presents an intelligent control strategy for photovoltaic (PV), and multibattery bank for a DC microgrid in grid connected as well as isolated mode. The control objectives of the proposed scheme are to ensure load sharing based on the source capacity among sources, to reduce the power losses in the system, and to enhance the system reliability and power quality. The proposed energy management system controls the power sharing with the battery bank based on the state of charge of the battery. Then, it connects the loads to the nearest power sources to reduce the power losses in the lines. A graphical user interface (GUI) has been configured to demonstrate the controlling and monitoring of the DC microgrid and the operation performance of IEMS during various operating conditions such as distributed sources with lumped load and distributed sources with distributed load. The proposed IEMS shows the better operational performance for operating conditions in terms of voltage regulation, power loss, and reliability enhancement of the microgrid.
