混合型太陽光發電系統設計分析

Abstract

本研究旨在探討混合型太陽光發電系統最佳化設計，使系統具有最佳經濟效濟及性能表現。 因近年來石化能源日漸短缺以及對環境汙染問題，科學家不斷尋找可用之新能源，在發現核能存在太多淺在危機後，太陽能被視為目前最有希望之再生能源。目前太陽光發電系統經過多年努力，在成本上以及系統穩定度均達一定水準有其經濟效益。但在已太陽能發電廠達一定規模之國家如德國發現，因太陽能發電廠備載容量較大，在太陽光很強時，電網可能因無法負荷瞬間大電流而造成崩潰。 而為解決此台大新能源中新便開發可在市電與獨立型太陽光發電系統間切換的混合型太陽光發電系統。為的就是讓使用者可利用太陽光發電達到自給自足，但在天候狀況不佳時能夠切換市電持續供電並且不會影響電網運作。 為得到混合型太陽光發電系統之最佳系統匹配以及最佳發電效益，本研究採用模擬分析及實際驗證。先進行傾斜面輻射量模型推導，考慮各種影響發電因素，再進行系統發電模型的建構。接著配合梯型供電切換模型，進行供電切換的判斷。最後可得如:發電量、電池循環次數、供電切換次數等數據，用以決定最佳之系統設計。再利用實際架設於台大工綜管八樓之混合型太陽光發電系統所測得之實際數據與模擬數據進行驗證，以確保模擬之準確性。並在最後進行長程性能模擬以及示範如何找到最佳之系統匹配，以及對兩種實際個案情況做模擬分析。

In this study, it will include simulation and actual verification. First is deriving the inclined surface radiation model and considering various factors affecting power generation. Then construct the system generation model. Second with the ladder switching power supply model to judge the power switch. Last available such as: electricity, battery cycles, power switching frequency of the data used to determine the best system design. And finally the long-range performance simulation and demonstration of how to find the best match of the system, as well as the actual circumstances of the case made for both simulation analysis. This study aimed to explore the hybrid PV generation system optimized design that the system has the best economic efficiency and economic performance. In recent years, due to the growing shortage of fossil fuels and the environmental pollution problem, scientists are constantly looking for new energy sources available, the presence of too much light in the discovery of nuclear energy after the crisis, solar energy is considered as the most promising of the renewable energy sources. At present, solar power generation system after years of efforts, the costs and the stability of the system has reached a certain level of its economic benefits. But solar power plant has reached a certain scale of countries such as Germany found that due to a large solar power plant equipment load capacity, strong sunlight, the grid may be due to inability to load moment caused by the collapse of a large current. And to solve this NTU has developed a new energy in the new hybrid solar power generation system between the mains and the independent solar power generation system switching. As is so that users can take advantage of solar power generation to achieve self-sufficiency, but in poor weather conditions continued to be able to switch the mains power supply and does not affect the operation. To get the best system to match the hybrid solar power generation systems and best power efficiency. In this study, it will include simulation and actual verification. First is deriving the inclined surface radiation model and considering various factors affecting power generation. Then construct the system generation model. Second with the ladder switching power supply model to judge the power switch. Last available such as: electricity, battery cycles, power switching frequency of the data used to determine the best system design. And finally the long-range performance simulation and demonstration of how to find the best match of the system, as well as the actual circumstances of the case made for both simulation analysis. And at last, the long-range performance simulation and demonstration of how to find the best system to match, as well as the actual circumstances of the case made for both simulation analysis.
