Renewable energy has become somewhat popular recently among few years. In-dependent DC Microgrid (MG) systems now have increasing capacity for producing renewable energy. The main cause is the possibility to generate affordable, environmentally beneficial, clean energy. Solar PV, lithium-ion battery; supercapacitor (SC) and fuel cell (FC) have been used in this proposed MG. This study proposes an Energy Management System (EMS) to reduce the energy loss of a stand-alone DC MG. State of Charge (SOC) based changing and discharging controller integrated to the EMS so that it can increase the longevity of the Energy storage system (ESS). In this system lithium-ion battery and SC are considered as a ESS. MATLAB Simulink R2023b software has been used to verify the proposed system.

摘要

Renewable energy has become somewhat popular recently among few years. In-dependent DC Microgrid (MG) systems now have increasing capacity for producing renewable energy. The main cause is the possibility to generate affordable, environmentally beneficial, clean energy. Solar PV, lithium-ion battery; supercapacitor (SC) and fuel cell (FC) have been used in this proposed MG. This study proposes an Energy Management System (EMS) to reduce the energy loss of a stand-alone DC MG. State of Charge (SOC) based changing and discharging controller integrated to the EMS so that it can increase the longevity of the Energy storage system (ESS). In this system lithium-ion battery and SC are considered as a ESS. MATLAB Simulink R2023b software has been used to verify the proposed system. The proposed EMS performance validated considering different cases. The simulation proved the approach’s practicality, efficiency, and EMS capacity for a DC MG running in several modes. The new EMS is more reliable and performed better than conventional ones; energy management and energy interchange reduced major energy use. Furthermore, the proposed EMS for DC MG operates effectively.
