Implementation of Central Level Controller for Integrated Wind and Solar Based Hybrid Power Generation Scheme with Storage System

Abstract

Nowadays the abnormal sudden change in climate and the global warming are the biggest threats to our human community. The vast population and their pollution along with the conventional method of power generation scheme are the root cause for these problems. To overcome these issues the renewable energy conversion system (RECS) (wind, solar, etc..) is the alternative solution. The wind power system is the second largest renewable natural resource (after hydropower). The availability and reliability are the biggest drawbacks of RECS. Due to this problem, the continuity of supply gets disturbed. At this Juncture, an autonomous intelligent control system is required to control the process of RECS. newlineTo strengthen the RECS, the integrated wind and solar-based energy conversion system are developed along with a battery storage system (BSS) to deliver an interrupted power supply to a load. The amount of power generated from the RECS is purely dependent on environmental changes only. To follow these changes and make a RECS reliable under robust conditions is a challenging task. At this juncture, the central level controller (CLC) is introduced and proposed to utilize renewable resources in an effective way. In all existing system, the power converters like DC to AC inverter and DC to DC converter only works under the closed-loop system. However, in the proposed method the entire power generating system comes under the closed-loop system. The following parameters like wind velocity (v) which is the important parameter in wind energy conversion system (WECS), similarly solar irradiation (G) in solar energy conversion system (SECS), state of charge (SOC) of BSS, and load Position (either in on state or in off state) are taken into the account to make a decision. Along with this single-stage boost inverter (SSBI) is enabled to convert the 48V DC supply to 230 V AC supply.
