Abstract
The increasing penetration of natural gas power generation and developing power-to-gas (P2G) technique in recent years have promoted the coupling between the power supply system and the natural gas system than ever before. Given the background, this paper studies the collaborative planning of integrated energy system with gas turbines and P2G stations. First, the energy hub concept is introduced and modeled. A model for an integrated energy system with multiple interconnected energy hubs is next presented. Then, this paper takes the minimum overall cost as planning objectives including investment cost, operation cost and energy shortage cost characterizing the reliability of the integrated energy system, optimizes the capacities of wind generation units, traditional generation units, gas turbines, P2G stations with particle swarm optimization. Case study verified the effectiveness of collaborative planning in economy and reliability of integrated systems.
