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.
Because of the fundamental uncertainties inherent in microgrid design and operation, researchers have created battery and microgrid models of varying levels of complexity, depending upon the purpose for which the model will be used.
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.
For all scenarios discussed in this paper, the load and PV power inputs are eighteen days of actual 1-min resolution data from an existing microgrid system on an island in Southeast Asia, though any load profile can be used in ESM. The load has an average power of 81 kW, a maximum of 160 kW, and a minimum of 41 kW.
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.
For example, if a battery is replaced when it falls to 80% of original capacity and microgrid operation requires a certain battery capacity, the battery must initially be oversized by 25% to maintain the desired capacity at the end of the battery’s life.
