Optimal Dispatch for Regenerative Electric Heating Considering Renewable Energy Accommodation

Abstract

To solve the problems of high-intensity heating demand in northern areas and the urgent need to accommodate a large amount of renewable energy, an optimal dispatch model of regenerative electric heating is studied in this paper. Firstly, the dynamic model of electric heating storage device and the thermal load characteristic model are established. Then, with the objective of minimizing the total cost of system operation, an optimal dispatch model for the regenerative electric heating to participate in renewable energy accommodation is proposed. According to the results of the case studies, the optimal dispatch model proposed in this paper can effectively solve the problem of renewable energy accommodation. The results also verify that re-generative electric heating has the operating characteristic of “storing heat in low valley period and all-day heating”, which shows its economy and adaptability.
