Customer ServiceEnergy 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.
Lithium-ion (Li-ion) batteries are the most highly developed option in size, performance, and cost. A broad ecosystem of manufacturers, system integrators, and complete system providers supports Li-ion technology. However, the vendors best equipped to bring value to microgrids bring the right components to each project.
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.
