Abstract  Under the background of the rapid development of integrated energy system (IES), a multi-objective planning model of electricity heat hydrogen integrated energy system considering the uncertainty of wind speed and solar radiation is proposed. Firstly, this paper presents the structure framework and key equipment operation strategies of electricity-heat-hydrogen integrated energy system model. With the shortcomings of the existing power to gas (P2G) technology and the combined heat and power (CHP) operation mode, some improvement measures are proposed, such as the hydrogen produced by P2G is preferentially supplied to fuel cell vehicles, and switching CHP operation mode according to the renewable energy output. Secondly, in order to solve the impact of uncertainty of renewable energy output on system planning, the uncertainty scenario description is implemented based on the scenario method. A multi-objective optimal planning method considering the uncertainties of wind speed and solar radiation is proposed, which can deal with the impact of uncertain factors and taking into account the economy, efficiency and reliability. The optimization objectives are the minimum economic cost, the maximum utilization rate of renewable energy and the minimum energy not supply. At last, the improved hybrid multi-objective particle swarm optimization algorithm and fuzzy membership function are used to solve the equipment capacity configuration scheme. The results verify the effectiveness and rationality of the proposed method in this paper.
