Fuzzy Logic Controller Strategy for Ameliorating DC Link Voltage for Grid Connected Hybrid PV-Wind Generation Systems

Abstract

In order to overcome these disadvantages, hybrid interconnection of Solar and Wind systems is proposed for a three phase grid connections. To improve the system’s functionality, this proposed combination circulation device contains sunlight as well as wind energy systems that need to be combined to the grid at an Aspect of Popular Coupling (PCC). If you want to obtain the greatest electrical power under all weather conditions, an easy Maximum Power Point Monitoring (MPPT) protocol is worked with each photovoltaic and also wind system. The 3 phase diode clamped multilevel inverter, which is handled due to the unclear logic controller (FLC) based upon angle control procedures, is carried out to manage the DC-link at the intended current. The experimentations on accomplished on software application platforms to assess the efficacy of the proposed method. The outcomes display a superior performance of FLC compared with conventional PI controller in improving the step response of dc link voltage. Additionally, this control technique effectively sustains the constant grid voltage and ensures unity power factor regardless to the weather conditions even when combined with the solar-wind hybrid power system’s injected active electricity.
