A Progressive Approach of Designing and Analysis of Solar and Wind Stations Integrated with the Grid Connected Systems
Abstract
This article illustrates the advanced control strategy and analysis of hybrid resources integrated to grid system. The hybrid resources consist of solar station and wind station, which are integrated to the grid through AC bus system. The Perturb and observe algorithm (P&O) is used in Maximum Power Point Tracking (MPPT) to increase the power output of PV station and Wind station to maximum. The modeling and analysis of the system is improved using fuzzy based optimization is done in MATLAB/SIMULINK platform. The effectiveness of the system is improved using fuzzy algorithm during different load conditions. The improvements of grid voltage, grid power and grid currents can be observed during different load conditions from conventional PI controller to fuzzy logic controller. The advanced controller efficiently maintains the grid parameters stably in the hybrid systems.
