Fuzzy Based Grid Synchronization Method for Distributed Energy Resource Converters
نویسندگان
چکیده
Now a days, renewable energy resources such as solar Photo Voltaic (PV) cells, fuel cells (FC) and wind turbines(WT) plays an important role in generating electricity nearer to local loads that are integrated to utility grid. For integration of distributed energy resource converters to utility grid, a synchronization i.e matching of frequency, phase, amplitude of output voltages, active power and reactive power must exist in between output of distributed energy resource converters and utility grid. The main objective of this paper is to maintain synchronism between the output of distributed energy resource converter with utility grid. In this paper a fuzzy based grid synchronization method is proposed to achieve the synchronization. The proposed method is modeled and simulated in MATLAB/SIMULINK Software. Keywords— Distributed Generation Systems (DGSs), Grid Synchronization, Microgrid, Fuzzy Logic Controller.

Model Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation
This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...

In this paper, the synchronization of a new hyperchaotic complex system based on T-S fuzzy model is proposed. First, the considered hyperchaotic system is represented by T-S fuzzy model equivalently. Then, by using the parallel distributed compensation (PDC) method and by applying linear system theory and exact linearization (EL) technique, a fuzzy controller is designed to realize the synchron...
