Research on Multi-Energy Complementary and Optimization Control Technology of Urban Energy Internet

The research on multi-energy complementary and optimal control of urban energy internet is an inevitable trend of urban development. It can realize the efficient use of comprehensive energy at all levels in order to increase consumption of clean energy effectively and ensure stable supply of urban energy. Focusing on the research of multi-energy complementary and optimal control of urban energy internet, firstly, this paper introduces the key technologies and layered structure of urban energy internet. Secondly, based on preliminary understanding of energy internet, the primary methods of multi-energy complementation are considered, and the Cyber-Physical Systems based on characteristics of distribution network is proposed. Finally, the multi-objective particle swarm optimization algorithm is used to optimize the combined output of wind, hydro and thermal power in urban energy internet. This paper looks forward to achieve clean, safe, convenient and efficient energy utilization in urban areas with increased proportion of renewable energy incorporating energy into the impact on the urban power grid.
