Day-ahead economic optimization scheduling model for electricity–hydrogen collaboration market

This paper presents a day-ahead economic optimization scheduling model for Regional Electricity-Hydrogen Integrated Energy System (REHIES) with high penetration of renewable energies. The electricity-hydrogen coupling devices are modelled with energy storage units and Insensitive Electrical Load (ISEL). The proposed objective function is able to capture the maximum benefits for REHIES in terms of economic benefits and can be summarized as a Quadratic Programming (QP) problem. The simulation verification is performed by MATLAB/CPLEX solver. The simulation results show that the proposed optimization model adapts the market requirement by contributing flexible collaboration between electricity and hydrogen. Also, the translational properties of ISEL can implement higher economic profits and more effective utilization of renewable energy. (C) 2022 The Author(s). Published by Elsevier Ltd.
