The integrated community energy system (ICES) has aroused considerable attention for its low emission and high operating efficiency. The existing planning methods for ICES with multi-energy sectors ignored the deferrable load. In this paper, a two-stage planning method of ICES is developed to achieve the minimum annual investing and operating cost. At the first stage, the capacities of components in ICES are optimized to minimize the annual investment cost of ICES. At the second stage, the annual operating cost including the electricity and gas purchase costs and the component maintenance cost is minimized to satisfy the energy load. The deferrable load under the time-of-use energy price in seasonal typical days is considered in the second stage. Relevant simulations are conducted to validate the effectiveness of the proposed planning method for ICES. Considering the deferrable load, comparative simulations illustrate that the proposed planning method can significantly reduce the battery investment cost.
