Abstract: On-site generation microgrids may be a viable option for powering remote areas without grids. These microgrids differ from electricity grid-connected ones. Microgrids without main grid connections employ the same energy management technologies as those connected, including economic dispatch and unit commitment modules. Dynamic economic load dispatch (DELD) in isolated microgrids is the study's goal. These microgrids use load shedding as a last resort to balance supply and demand, allowing responsive loads and renewable electricity to be curtailed. The quantity of electricity made by dispatchable distributed generators (DGs), power cut by renewable DGs, power shed, and demand cut are determined for each time period. The well-known modified red deer optimisation (MRDO) approach is utilised to solve the DELD problem. In a microgrid with two renewable DGs and four dispatchable DGs, MRDO beats PSO, and demand response considerably lowers microgrid maintenance costs.
