A Combined Source and Demand-Side Energy Management System for a Grid-Connected PV-Wind Hybrid System

Besides the development of the design of the renewable hybrid system and its configuration, there is the topic of power management which responds especially to the renewable intermittency issue. Indeed, we are interested in the energy optimization of a hybrid system by managing instantly the energy produced and consumed by the architecture’s components. Our proposed plays a very important role for smart houses that will be the basis of a smart city in the near future. Indeed, we considered a PV-Wind-Battery hybrid system as a primary source that enables the house to satisfy its own energy needs while considering the grid only as a storage facility with infinite capacity. The connection of various components is done via the proposed hybrid architecture, and the different electrical switches mentioned on it are efficiently conducted by our proposed energy management system. Our proposal is a combination of energy management in an optimal way whether on the load or source side. The results showed that the source-side management system is efficient at all times to distribute the energy produced. Otherwise, the internal control of the different types of load is efficient during its launching during critical cases.
