In this paper

an island integrated energy system (IES) combining power

heat and hydrogen (CPHH) is built

and optimal power-heat-hydrogen scheduling is studied under actual plateau meteorological data. Considering the comprehensive demands of residents

an IES including renewable energy sources (RESs)

fuel cell

electrolyzer

electric boiler

thermal energy storage device and new energy vehicles is established and operated. In the first stage of operation

according to the prediction of RESs and demands

day-ahead optimization is carried out which aims to minimize operation cost

while electric vehicles (EVs) are considered as special demand response (DR) loads. For the second stage of operation

ultra-short-term prediction is implemented to provide prediction data for model predictive control (MPC)

realizing real-time operation. Functioning as a CPHH system

the fuel cell and electrolyzer collaborate to meet various needs of the plateau residential area with high efficiency. In addition

the method and IES structure proposed in this paper is compared with other options.
