Abstract
The paper presents the comparative techno-economic analysis of AC and DC microgrid systems. Both microgrids consist of PV–wind renewable energy sources (RESs) based generating system, battery bank to store and supply the excess electricity and a diesel generator for reliable operation under the absence of intermittent generation. The performance of the two types of microgrids has been evaluated using real load profile, actual prices of components, and realistic wind and solar resources data. The load profile of the business organization (IT building) of the city Hyderabad in India has been considered. The results include the response of microgrid in the day of summer and winter, various generators electricity generation response, overall cost of AC–DC microgrid under the given scenarios, detail comparison between the various components cost and battery state of charge. It has been validated through simulations that DC microgrid system requires lesser converter unit as compared to AC microgrid system. Further analysis revealed that DC microgrids are economically more feasible as compared to AC microgrid and reduce the losses significantly which are associated with AC–DC conversion in several applications of electric power system.
