Practical Day‐Ahead Gas Generator Dispatch Optimisation for Enhancing the Reserved Capacity

ABSTRACT In order to reduce carbon dioxide emissions, traditional coal‐fired power generation has been strictly limited in China recently, which has led to the problem of reserved capacity shortage. As one of the critical east provinces of China, Zhejiang province also suffers from the shortage of reserved capacity, whereas gas power generation is commonly utilised to mitigate this problem. However, the gas generator dispatch plan is still made manually at the current stage, which is quite time‐consuming and has the space to optimise. Therefore, this paper first proposes a practical day‐ahead gas generator dispatch optimisation (GGDO) model to maximise the daily minimum reserve capacity. Besides, several constraints related to the system operation and natural gas limitations are given. Finally, the data of three typical days in Zhejiang province are employed for demonstration, which shows the strength of the proposed GGDO model.
