Energy management system controller integrated with solar photovoltaic for smart energy utilization

Abstract

Continuous growth of global electrical energy consumption and the echo of global warming related issues have signaled research community to search an alternative way to generate and to efficiently manage the generated energy. Thus, engineering researches in Renewable Energy (RE) and Energy Storage Systems (ESS), especially Battery Energy Storage System (BESS) have been recognized as primary solution and having an assurance in generating, storing and using the electrical energy at optimum level, besides improving the grid utilization. With the presence of RE and BESS in a power system, it is necessary to have a controller which acts as the brain to interface all the system efficiently. Hence, the design and development of a controller become very crucial and need careful execution in order to meet the requirements for functionality, simplicity, portability, reliability as well as less cost. Therefore, this research is dedicated to design and develop an energy management system controller for BESS integrated with solar Photovoltaic (PV) system for smart energy utilization, which is based on load leveling and peak shaving applications for real-time AC power management. The main function of the controller is to monitor the load demand profile and trigger the battery to either charge from the solar PV or discharge to produce a leveled or shaved load profile that will be seen at the grid network, while maintaining the actual load demand usage.
