The power of the PV power generation and EV charging units in the integrated standalone DC microgrid is uncertain. If no reasonable countermeasures are taken, the power variation will lead to a significant deviation in bus voltage and reduce the stability of the microgrid system.
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 energy management of the integrated DC microgrid consisting of PV, hybrid energy storage, and EV charging has been analyzed and investigated. Different control methods have been employed for different component units in the microgrid. An MPPT control based on the variable step perturbation observation method is designed for the PV array.
When the system power changes, the bus voltage will also change. An effective control strategy for the energy storage unit in the microgrid is needed to stabilize the bus voltage within a specific range. The DC microgrid shown in Fig. 1 contains two different energy storage devices, supercapacitors and batteries.
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.
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.
