Planning Method for Regenerative Electric Heating System Considering the Heat Load during Power Outage

A two-layer planning method for regenerative electric heating considering the heat load during power outage was proposed. Firstly, the model of regenerative electric heating system was established. Then, the heat load model during power outage was established. On this basis, the optimal planning model was proposed, which took the minimum daily operation cost as the objective function. Finally, a typical regenerative electric heating systems was used as a test system to illustrate the effectiveness of the method. The case results showed that the proposed method can effectively satisfy the heat load during power outage.
