可再生能源傳輸 — 先進鉛碳儲能系統(tǒng)改善電網(wǎng)傳輸

摘要：先進鉛碳儲能系統(tǒng) （ALCESS）是特別適合增長中的可再生能源電網(wǎng)傳輸。一般來說，電網(wǎng)堵塞限制了低成本的再生能源為負載供電。最有效改善低成本的再生能源向城市地區(qū)供電的途徑是減低傳輸上瓶頸堵塞。在這種應用中，先進鉛碳儲能系統(tǒng)安裝在堵塞的地方，當有緊急事故時，它提供備用儲備能源，因此它使事故后的堵塞點減低所要增加的容量。當先進鉛碳儲能系統(tǒng)只是周期性的部署，緊急事故時，它使系統(tǒng)營運者可利用較大份額的堵塞點傳輸容量。 因此，能減低安裝地點的堵塞和促進低成本的再生能源的使用。 敘詞：儲能 先進鉛碳儲能系統(tǒng) 閥控式鉛酸電池 電網(wǎng)傳輸 Abstract：Advanced Lead Carbon Energy Storage Systems (ALCESS) are particularly well suited for increasing renewable energy transmission in the electric grid. In general, congestion on the grid limits the flow of low marginal cost renewable generation to load. Reducing congestion at transmission bottlenecks is the most effective way of improving flows of low cost renewable generation to urban areas. In this application, the ALCESS is located at a congestion point to provide back-up energy storage during a contingency event thereby allowing the congestion point post-contingent limit to be increased by the capacity of the energy storage system. While the ALCESS is only deployed periodically, during a contingency, it allows the system operators to utilize a greater fraction of the congestion points transmission capacity　thereby reducing congestion at that location and facilitating the flow of low marginal cost renewable generation.　 Keyword：Energy storage, ALCESS, VRLA, Network transmission
