Distributed Economic Dispatch for Port Energy Systems with Offshore Wind

Offshore wind energy is a widely applied clean energy source and an important pathway to achieve port decarbonization. It ensures the sustainable development of the marine economy. This paper proposes a distributed economic dispatch strategy for port integrated energy systems considering offshore wind power to reduce port carbon emissions and promote sustainable development. Firstly, considering the distributed characteristics of heterogeneous energy supply equipment in ports, a Port Integrated Energy system is established. Secondly, the transmission losses exist in the power lines of offshore wind farms, an optimal schedule model of PIES considering offshore wind farms is developed. Then, based on distributed mixed-integer linear programming, a distributed algorithm is proposed. Finally, the effectiveness of the proposed method is verified through simulation.
