Standalone hybrid generation system for the remote area of Thar, Pakistan CHAPTER – 4: Implementation, Modeling And Simulation of the Hybrid Generation System. In this chapter implementation and modeling of the Wind turbine and Photovoltaic, and their corresponding subsystems (MPPT for PV, converters, etc.) have been simulated using “simpowersystem” toolbox discussed in chapter-2. The models for PV, wind turbine and converters have been modeled using literature review discussed in chapter -2 and the system architecture used for the hybrid generation system is Mixed Coupled HPS. The main idea behind this simulation is to demonstrate the system working in MATLAB environment and analyzes the simulation results. Firstly, all the models are simulated individually and then integrated to became a hybrid generation system 4.1. Proposed System Design Any combination of renewable energy technologies with an optional backup diesel engine and storage device is possible though some of them may not be most efficient, cost effective and reliable. The way to determine the most appropriate technological solution for hybrid systems always requires a feasibility study based on gathering the field data for each specific site and on life cycle cost analysis of each components and the system. Different factors may be taken into account while considering choosing the best coupling layout of different energy sources, like geographical location of the site (windy, sunny etc.), types of energy sources (Wind, PV, Genset, etc. or mixed), the nature of load demand (more demand at daytime or at nighttime, all time load), and the efficiency of power electronics devices used in the conversion of power. From the location analysis of the system we can say that as the location has abundant renewable resources but these resources vary as when there is full sun, we don’t have enough wind mostly during day time and similarly during night time more wind and no solar irradiation hence based on the renewable resources availability, power electronics efficiency, cost effectiveness and design sustainability a mixed coupled HPSs is the best option to be considered. A detailed explanation of the mixed hybrid system is already explained above in chapter -2. Below is block diagram of the proposed design used in the system. tải về 6.62 Mb.
