Abstract:

As a new energy storage technology, reversible solid oxide cell (RSOC) can promote the renewable energy consumption and improve the system efficiency. Therefore, a capacity planning method of an integrated energy system of wind photovoltaic and hydrogen based on RSOC is proposed. Firstly, the planning model of the integrated energy system of wind photovoltaic and hydrogen is established, considering the constraints of the high energy consumption of the balance of plant (BOP) system and the limited power regulation of the RSOC system. Secondly, the particle swarm optimization (PSO) algorithm is used to solve this planning problem, aiming at minimizing the annual redundant and lacking power, and investment cost. Finally, the system planning sensitivity analysis is performed for the uncertain factors of the RSOC cost and hydrogen price. The simulation results show that the proposed method can obtain a reasonable configuration scheme, greatly reducing the redundant and lacking power and improving the flexibility of the system resource allocation.
