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 DC bus is connected to the AC bus through the DC/AC inverter. The energy management system tracks load demand, available PV power and battery energy level, and it controls charge/discharge status of the battery and decides whether to demand energy from the grid. Figure 2. The architecture of the microgrid system.
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.
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.
The combination of energy storage and power electronics helps in transforming grid to Smartgrid . Microgrids integrate distributed generation and energy storage units to fulfil the energy demand with uninterrupted continuity and flexibility in supply. Proliferation of microgrids has stimulated the widespread deployment of energy storage systems.
