计及阶梯碳势综合需求响应和动态绿证-绿氢协同交易的掺氢氨综合能源系统低碳调度OA

With the increasing penetration of renewable energy into energy systems,enhancing renewable energy accommodation and achieving low-carbon system operation have become increasingly important.To this end,a low-carbon optimal scheduling strategy for hydrogen-ammonia-blended integrated energy systems is proposed,considering tiered carbon potential demand response and dynamic green certificate-green hydrogen collaborative trading.First,to enhance green hydrogen utilization,hydrogen-blended gas firing and ammonia-blended coal firing are introduced to establish a high-efficiency hydrogen and ammonia utilization model.Second,based on the carbon emission flow theory,a multi-energy demand response model considering tiered carbon potential is constructed by combining dynamic carbon emission factors with multi-energy loads on the demand side.Then,the coupling and complementary relationship between green certificate trading mechanisms and green hydrogen certificate trading mechanisms is analyzed.Finally,by considering the supply-demand characteristics of trading prices,a dynamically responsive green certificate-green hydrogen collaborative trading mechanism is proposed,thereby formulating a low-carbon economic dispatch model for integrated energy systems involving hydrogen-blended gas and ammonia-blended coal.Case studies under different scenarios verify the effectiveness of the proposed scheduling strategy in improving the accommodation level of green power and green hydrogen as well as carbon reduction in both generation and load sides,achieving low-carbon and economic operation of the system.
