Optimal Planning Of Industrial And Residential Micogrids

Microgrids have benefited the power systems to get riddance from the prolific usage of conventional energy resources by substituting with distributed generations(DGs).Utilizing DGs in microgrids not only provides clean and green energy but also reduces the gigantic transmission and distribution lines losses.Vast introduction of renewables in microgrids saves customers from the huge fuel prices and also provides a sustainable substitute to the future depletion of fossil fuels.Microgrids have been proved as the most emerging and advanced electrical power systems due to novel ability of operating in both grid-connected and isolated mode.Microgrids use multiple energy resources together and cogeneration can compensate the renewables' intermittent behavior.Microgrids have also ability to purchase power from the main grid in case of unavailability of power from own resources and selling power to the main grid in case of abundant power available which results in revenue earning as well.In this thesis,the industrial microgrid and residential microgrid with annual load growth are planned which contain nondispatchable generations(Solar,Wind),dispatchable generation(Diesel)and energy storage unit where all the energy resources are mixed together and optimized.So,the optimal planning and optimization of microgrids is very significant in order to meet the load demand economically with clean and green energy and the objective of this research is to reduce the hefty investment cost,operation and maintenance cost of the microgrids.Furthermore,in order to verify the different behavior of both microgrids,four typical days are chosen to represent a whole year forecasted data for the load demand,solar power and wind power while the power output curves for each typical day are analyzed one-by-one in every year both in the isolated and gridconnected mode.
