Abstract

The operation of community integrated energy systems (CIESs) is challenging because it is necessary to satisfy multiple energy demands with considering multiple links including energy production, storage and consumption. This paper formulates the optimal scheduling strategy of a real CIES in China based on detailed modelling of kinds of chillers and thermal storage devices. The flexibility effect of storage devices is fully utilized in the scheduling strategy and the impact of the tie-line power to the distribution network is reduced by adding the peak-valley difference penalty to the objective function. Case studies are conducted based on the data for a typical day in summer. The results show the proposed strategy can realize an economic and reliable operation by coordinating various energy devices. And the tie-line power is well smoothing with a lower ratio of the peak-valley values.
