Integrated energy system(IES)is a key platform to promote the adjustment of energy structure.Reasonable planning can effectively improve the operation economy and system stability of IES.In addition

due to the inherent randomness and intermittency of renewable energy generation and the peak and valley characteristics of load

the output fluctuation of multienergy coupling equipment in IES seriously threatens the operation stability of IES.To cope with the above challenges

aiming at the economical and stable operation of IES

this paper establishes a multi-objective optimization planning model for the electric-hydrogen hybrid energy storage system(ESS)with the goal of minimizing the configuration cost

system voltage deviation and net load fluctuation of IES.Under the IEEE-33 standard test system

the model is solved by the multi-objective artificial hummingbird algorithm(MOAHA)for optimizing the capacity and location of the electric-hydrogen hybrid energy storage system. Simulation results show that the proposed optimization planning method can effectively improve the voltage distribution and net load level of IES distribution network

and enhance the operation flexibility of IES by relying on the complementary characteristics of electric-hydrogen hybrid energy storage.
