Real-time Optimal Dispatching of Electricity-Gas Joint Coordination Considering Integrated Energy Interconnection

Wei Xiong, Xianshan Li, Shiwei Su

Abstract


In the Energy Internet, users no longer have a single demand response for electricity, but an integrated demand response for multiple types of energy. In integrated demand response, users participate in demand response directly by switching energy sources without having to change their energy usage time habits. A mathematical model of the electricity-heat-gas energy circuit, based on the correlation between different energy sources, considering the combined demand response economy and comfort of the household user. Real-time dispatch optimization modeling with the objective of real-time peak shaving within a day and tariff regulation as a means to provide a decision basis for real-time peak shaving and smoothing of the electricity load curve. An example is given to verify the effectiveness of the model and the feasibility of the solution method, at the peak of electricity consumption around 8 p.m., through real-time dispatching, the peak electricity load decreases by about 2 kWh, and the gas consumption increases slightly. And the economic basis of integrated demand response scheme decision-making is analyzed.
