Economic Dispatch on Microgrid by using Cuckoo Search Algorithm

In this modern science world, the usage of power is very high. As the usage is increased, the power demand is also gets increased. In order to comprise/compensate the power demand, different forms of power sources are preferred. Dispatchable energy resources (non-renewable energy sources) are the sources can be turned on and off in short amount of time and it is generated from different techniques. Non-dispatchable energy resources (renewable energy resources) include the nuclear power plants, hydroelectric plants, and wind and wave energy resources. The Distributed Energy Resources (DER) typically use these renewable energy sources, including small hydro, biomas, solar power, wind power and geothermal power for an electric power distribution system and DER is coordinated within a microgrid. A Microgrid is a localized group of electricity generation, energy storage and loads that operates connected to a centralized grid (macrogrid). This work focuses on to minimize the total operation cost in microgrid. Here, the operating cost is optimized by using a new cuckoo search algorithm. Cuckoo search is a meta-heuristic algorithm. The algorithm is implemented using MATLAB package.
