Real-time Optimal Operation of Microgrid with Power-to-hydrogen

Abstract

Hydrogen plays an important role in the decarbonization of the future energy system. Power-to-hydrogen (PtH) is considered an essential connection between electric power system and hydrogen energy system. However, there are few works on the real-time operation of the above two systems. This paper proposes a real-time optimization operation model for the microgrid with the power-to-hydrogen device. In the model, hydrogen is produced by PtH device and stored in the storage tank, which then powers fuel cell electric vehicles. Model predictive control (MPC) and myopic policy are adopted to solve the optimization problem. Finally, several cases are designed to indicate the effect of PtH device and the performance of different algorithms. Results show that in the microgrid with hydrogen demand, PtH device can improve the operation economy and reduce the operational cost. Besides, MPC performs better than myopic policy in real-time optimization.
