Optimal configuration of park-level integrated energy system considering integrated demand response and construction time sequence

Park-level integrated energy system (PIES) is a typical application of multi-energy coupling and supply, whose configuration can effectively improve its energy efficiency. A PIES optimal configuration model considering integrated demand response (IDR) and construction time sequence is proposed in this paper to further stimulate the multi-energy complementary and improve the planning economy of PIES. First, PIES considering IDR is modeled and the mathematical models of energy conversion and storage devices are established. Then, the PIES configuration model considering IDR and construction time sequence is established. Finally, a case study on an electric-heat coupling commercial PIES is carried out to demonstrate the effectiveness of the proposed model, which shows that the proposed model is effective in terms of improving the device utilization rate, cutting the planning costs of PIES and realizing "peak-cutting and valley-filling".
