Customer ServiceThe purpose of this study is to make evaluation regarding significant issues about the customer expectations and technical competencies for successfully integration of batteries in microgrid systems.
Customer ServiceBecause 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.
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.
In a standalone microgrid system, prolonging the life of the equipment is necessary to reduce the cost of its replacement. However, the size and installation costs of the storage systems must be appropriate. Therefore, this paper provides an appropriate weighting to minimize the cost of the microgrid system.
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.
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.
