Energy Management Systems (EMS) have been developed to minimize the cost of energy, by using batteries in microgrids. This paper details control strategies for the assiduous marshalling of storage devices, addressing the diverse operational modes of microgrids. Batteries are optimal energy storage devices for the PV panel.
The system consists of a programmable logic source and variable 10 kW and 5 kW loads on the grid side. The microgrid consists of a battery source, an inverter and an AC load with the same ratings as in the grid. The microgrid has two modes of operation — On-grid mode and Off-grid mode.
The battery storage system is connected to the microgrid using a PID controller. The electrical grid, connected to the DC_Bus through AC/DC converter, will be used only in emergency cases (when the renewable power is not enough) and the battery state of charge is less than 20%.
The proposed system control is based on the optimum power supply of loads through the available renewable sources and the battery State of Charge (SOC). The microgrid measurement data is transmitted through the Python platform and a graphical user interface (GUI) software developed for data analysis.
A shunt active filter algorithm for improving the power quality of grid is also implemented with power flow management controller. The overall management system is demonstrated for on grid and off grid modes of microgrid with varying system conditions. A laboratory scale grid–microgrid system is developed and the controllers are implemented. 1.
In addition, the graphical representation of each parameter related to the proposed microgrid operation and energy management system can be monitored. Therefore, it is mentioned that the using the proposed interface technique, the system operators may monitor the microgrid operation and energy consumption anytime from anywhere.
