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

Abstract

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.

Research on the generation mechanism and characteristics of an Energy Internet backbone network

“…③ The network diameter (5,7,9) constructed in this paper is much smaller than the traditional grid (46), and it is also smaller than the Internet diameter (11).…”

“…Home energy LAN is an energy management network at the level of family buildings, including renewable energy power generation equipment, distributed controllable power generation equipment, energy storage system, and various intelligent loads [6]. The urban Energy Internet emphasizes future energy supply and consumption operation patterns and energy management models [7]. The regional Energy Internet focuses on the coupling of network systems such as power networks, electrical transport networks, natural gas networks, and information networks [8].…”

Research on Home Energy Management Method for Demand Response Based on Chance-Constrained Programming

“…Considering the electricity price and incentive to optimize the equipment usage time, the demand response model based on the home LAN is proposed in [22], and the related equipment is used to realize the application of demand response in household energy management. The main point of [23] is to propose a pricing method for the optimal energy consumption mechanism of smart grids in the future. A demand response model based on the supply and demand sides of Steinberg's game theory was proposed in [24].…”
