Modelling, implementation and performance analysis of a hybrid wind solar power generator with battery storage

Abstract

A wind-solar hybrid power generator system consisting of photovoltaic (PV) modules controlled by maximum power point tracking (MPPT) method and connected to a DC-DC boost converter, a grid-connected wind turbine coupled with a permanent magnet synchronous generator (PMSG) and connected to a back-to-back converter and also a bidirectional DC-DC converter, and finally an energy storage module (batteries) connected to a bidirectional DC-DC converter has been modelled, implemented and discussed in this thesis to achieve an efficient and cost-effective system configuration so that renewable energy power sources could improve the life of people in both urban and remote residential areas. The entire model is implemented in the MATLAB/Simulink environment. The behaviour of the proposed model is examined and the output voltage and power characteristics of the model obtained from simulations are analysed and optimized using the proposed control strategy. The model is further analysed from an economic point of view so that consumers planning to install the system can get an idea of the system costs.
