Research on Multi-Energy Coordinated Intelligent Management Technology of Urban Power Grid Under the Environment of Energy Internet

Integrated energy systems (IES) are an important physical carrier of the energy Internet, which undertakes the tasks of energy conversion, distribution, and storage of electricity, heat and cold. From the perspective of energy Internet, this paper studies the optimal operation scheduling of an urban power grid with a high proportion of clean energy and proposes a multi-energy coordinated intelligent management method for the urban power grid. Firstly, the structure and typical characteristics of urban energy Internet are researched. On this basis, the regulatory capacity of the adjustable generator set and the regenerative equipment is used to offset the volatility of renewable energy, the internal operating system, and network stable operation constraints are considered. To solve the model, alternating direction method of multipliers (ADMM) is used. Finally, a real-time power grid example is given to verify the effectiveness of the proposed method.
