Swetha Monica Research Scholar, Department of Electrical and Electronics Engineering, SRKR Engineering College, Bhimavaram, India ABSTRACT Use of Renewable energy sources for power production is increasing day by day. In this paper Fuzzy Neural Network is proposed to get regulated power from the renewable energy sources. A stand-alone hybrid power generation system consisting of solar and PMSG with AC load is designed in this paper. Additionally P & O algorithm for Solar and Hill climbing search algorithm for Wind are used as the control logic for the Maximum Power Point Tracking (MPPT). The proposed controller for inverter is intended to keep the load voltage and frequency as constant regardless of the renewable power generation. Comparative Simulation results with Fuzzy logic controller for inverter show the effectiveness of the proposed controller.

In recent years, renewable energy resources (RES) are becoming the world focus and grabbing the attention of many governmental organizations. Researchers consider renewable energy sources the promising energy sources amidst the fear of natural resource depletion and environmental issues such as high levels of CO 2 and other harmful emissions. Some of the other reasons comprise advantages like abundant availability in nature, eco-friendly and recyclable. Solar and wind energy are the world’s rapid growing energy resources compare to all renewable energy sources. Distributed Generation (DG) is a replacement for centralized power generation plants. Along with the use of DGs, by adding Battery Energy Storage (BES) the reliability of RES can be improved. The environmental conditions can change rapidly for example photovoltaic system is ideal for the places having more illumination levels and wind power system is ideal for locations having favourable wind flow conditions [3]. It is better way to use the hybrid source power system which is probable to endorse that hybrid stand-alone electricity generation systems are usually more reliable and less costly than systems that depend on a single source of energy [2]. The significant characteristic of hybrid power system includes, system reliability, operational efficiency [1].
