面向电-碳市场协同的负荷响应机制与效益分析初探

Preliminary Study on Mechanism and Benefit Analysis of Load Response for Electricity-Carbon Market Collaboration

为清洁高效地维护电网供需平衡,在电力市场考虑用电碳排放成本并构建市场化的源荷互动交易环境,提出负荷主体参与调控响应交易的用电碳排放核算模型、电-碳市场协同方式、用电碳排放成本核算及响应市场收益分析方法,通过弹性电价耦合需要调控响应的不平衡电量,实现跟踪调控响应需求而调整结算电价的功能。通过算例验证了所提电-碳市场协同机制和方法能够耦合不平衡电量,改变用电成本和碳排放收益,激励负荷主体参与调控响应。为负荷弹性资源纳入调控范畴、提高调控经济性和环保效益提供了市场化调控负荷弹性资源的价格手段和市场收益分析方法。

In order to maintain the balance between supply and demand of the power grid cleanly and efficiently, the cost of carbon emission from power consumption in the electricity market is considered and a market-oriented source-load interactive trading environment is built. Then, the accounting model of carbon emission from power consumption, the electricity-carbon market collaboration mode, the cost accounting of carbon emission from power consumption and the analysis method of responding market benefit for load subjects participating in the regulation response trading are proposed. By coupling the unbalanced electricity quantity that needs the regulation response by elastic electricity price, the function of tracking and adjusting the settlement electricity price in response to demand can be realized. The proposed electricity-carbon market collaboration mechanism and method are verified by an example, which can couple the unbalanced electricity quantity, change the electricity cost and carbon emission benefit, and encourage the load subjects to participate in the regulation response. The price means and market benefit analysis method of market-oriented regulation of load elastic resources are provided to bring load elastic resources into the regulation scope and improve the regulation economy and environmental protection benefits.
