Central Power Management System for Hybrid PV/Battery AC-Bus Microgrid Using Typhoon HIL

This paper presents a rule-based master/slave communication-based power management System (PMS) for a real-world grid-interactive AC-bus hybrid microgrid (MG) that incorporates photovoltaic and energy storage systems. The microgrid includes seven PV inverters, one battery inverter and AC load. The proposed power management system aims at minimizing the electricity costs for the customer as well as providing the load with a stable voltage, frequency and power supply in grid-connected and islanded conditions. Typhoon HIL Control Center has been employed for the implementation of the microgrid, SCADA interface and the power management system. The proposed power management system has been developed in Python, inside the SCADA environment and the microgrid has been simulated using the virtual HIL device.
