可再生能源是分布式电源的替代电源，可以产生清洁可靠的电力。印度有很大的潜力和丰富的风能供应，以产生低成本的电力。利用MATLAB时域仿真器对风电并网系统进行建模和分析。本文提出了一种新颖的单级AC到AC变换器，作为AC到DC到AC变换器系统的可行选择，作为分布式发电系统与电网或负载接口。提出了一种新的交-交变换器时间开关模式和控制策略.针对不同的风行为场景，展示了AC到AC转换器和控制器的动态行为。基于风的行为和AC到AC控制器的操作的研究得出结论，AC到AC转换器在技术上是将风力涡轮机与负载连接的替代选项。
Renewable energy is alternative power source for distributed power supply to produce clean and reliable electricity. India has high potential and abundant availability of wind energy to generate low cost electricity. This paper presents the modeling and analysis of load connected wind energy systems using time-domain MATLAB simulator. This paper contributes a novel single stage AC to AC converter, as a feasible option to AC to DC to AC converter system, to interface with grid or load as a distributed generating system. New Time switching patterns and a control strategy for AC to AC converter is presented. The dynamic behavior of an AC to AC converter and controller are demonstrated for different scenario of wind behavior. The studies based on the behavior of wind and operation of AC to AC controller concludes that an AC to AC converter is technically an alternative option to interface a wind turbine with load.
