Simulation and Analysis of Composite Wind/Solar Energy Transformation System: Enhancing Efficiency and Performance of Renewable Energy Systems

Abstract

Solar and wind are the most popular resources due to its ease of availability and its ease conversion into electricity. Each renewable resource require DCDC boost converter with MPPT control for power generation. To obtain high efficiency of photovoltaic (PV) system and wind energy system, the maximum power point tracking (MPPT) technology is employed. Perturb and Observe MPPT technique is used for PV system in which dc voltage is used as perturbation variable. While in wind energy system, perturbation variable as a dc current is used in modified perturb and observe MPPT algorithm. Modified perturb and observe algorithm is stable and tracks fast for sudden wind speed change conditions. Maximum Power Point Tracking (MPPT) technique used with boost converter extracts maximum power from the source when it is available. Simulation of both the renewable energy sources is carried out separately in PSIM 9.0 with different MPPT types of techniques.
