Low carbon power operation optimization in the park based on green power and voluntary emission reduction trading
To ensure the economy of power operation in parks and increase the proportion of clean electric energy,an optimization model of low-carbon power operation in parks based on green power and voluntary emission reduction transactions is proposed.This model comprehensively considers the purchase cost of green power and thermal power,the cost of photovoltaic power generation,and the income from voluntary emission reductions.The objective function is to minimize the total operating cost,and green electricity,thermal power generation and photovoltaic power generation are optimized with combination of random probability constraints in three stages:medium-and long-term,day-ahead and real-time.Based on the data of an enterprise park in Nanjing,the analysis results show that under the reasonable price of voluntary emission,the optimization model can slightly reduce the total operating cost of the park,and significantly improve the use ratio of clean electric energy and the park's ability to cope with disturbances.In addition,the impacts of the voluntary emission reduction price and confidence value on the optimization results are analyzed.
