Abstract

Hybrid energy system which includes photovoltaic (PV) arrays and wind turbine with synchronous generator (WT/SG) is considered in this paper. The structure of the system was designed according to the most popular and efficient scheme. It includes generation sources, a DC bus, power converters, a storage battery, and a load and stiff grid. Maximum power point tracking algorithms (MPPT) were developed to increase power generation of the PV array and wind turbine. MPPT algorithm based on fuzzy logic controller shows efficient performance for PV arrays. A eprturb and observe algorithm gives an opportunity to achieve maximum power from the wind turbine. Boost converter and active rectifier (AR) were used for power conversion with the PV arrays and wind turbine accordingly. Novel control strategy for active rectifier was introduced in the article. Here, an active rectifier was implemented with synchronous generator behavior, and this approach is called a virtual synchronous machine (VSM). The concept of virtual synchronous machine is an alternative method of grid feeding. The model of a VSM can emulate properties, such as damping and inertia. The virtual synchronous machine allows smooth synchronization in a grid-tied mode and shows high operation speed and accuracy. In this paper, an energy system is designed for 10 kW and all essential points, such as reliability, optimal control strategy and high efficiency are inherited in our system. Modelling was held in MATLAB/Simulink software package.
