Abstract

Decentralized distributed generation technologies based on renewable energy recourses such as Solar PhotoVoltaic (SPV)/ Wind Turbine Generators (WTG) address the major issues concerned with conventional diesel generators to a large extent and are therefore considered as emerging alternate power solutions to stand alone applications. Three stand alone WTG power systems using different energy storage technologies, i.e. WTG-Battery system, WTG-Fuel Cell (FC) system and WTG-FC-Battery system are optimized and compared in this paper. The analysis of such hybrid systems feeding a standalone load of 45.6 kWh/day energy consumption with a 2.3 kW peak power demand is carried out using Hybrid Optimization Model for Electrical Renewable (HOMER) software. Based on simulation results, it was found that WTG-FC-Battery hybrid system is most economic solution compare to either single storage system. Cost sensitivity analysis with wind speed is also performed in this paper.

采用混合储能技术的单机WTG系统尺寸优化与分析

基于可再生能源的分散式分布式发电技术，如太阳能光伏(SPV)/风力涡轮发电机(WTG)，在很大程度上解决了传统柴油发电机的主要问题，因此被认为是独立应用的新兴替代能源解决方案。本文对采用不同储能技术的WTG- battery系统、WTG- fuel Cell (FC)系统和WTG-FC- battery系统三种独立的WTG电力系统进行了优化和比较。使用可再生电力混合优化模型(HOMER)软件对此类混合系统进行了分析，该系统为45.6 kWh/天的独立负载提供能量消耗，峰值功率需求为2.3 kW。仿真结果表明，WTG-FC-Battery混合储能系统是两种单一储能系统最经济的解决方案。本文还进行了考虑风速的成本敏感性分析。
