碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 105 === Due to the disaster cause some region disconnect with the power company grid, causing the affected households temporarily without electricity, high penetration of grid-connected photovoltaic generation system will lead cause power grid instability due to its intermittent power generation, and the current cost of photovoltaic generation system with battery energy storage is more expensive, so that the photovoltaic generation system doesn’t contain energy storage system and has function of standalone is gradually concerned. In order to continue to provide power without battery power storage system and power grid abnormal power failure, this thesis will develop a single-phase three-wire household photovoltaic generation system with the function of standalone. The photovoltaic generation system is composed of a DC-DC boost converter and a three legs inverter. When the utility is normal, the photovoltaic generation system can perform MPPT for photovoltaic cell array. When the utility is failed, the photovoltaic generation system can disconnect with utility and work into standalone mode in a certain power continue to provide AC power to the load in the day. The hardware prototype of the proposed single-phase three-wire household photovoltaic generation system with the function of standalone is developed and tested to verify its performance, and the experimental results show that the performance of single-phase three-wire household photovoltaic generation system with the function of standalone is as expected.
