Model building of urban energy system and effect analysis of green low‐carbon transition under the background of carbon peaking and carbon neutrality

Abstract

Under the carbon peaking and carbon neutrality goals background in China, cities are the main force of energy consumption and carbon emission, and their low‐carbon transition development has become the primary task of urban planning. The transitional development of cities not only puts forward higher requirements for the output proportion of new energy, but also puts forward higher requirements for the flexibility of energy system. This paper proposes an optimization model of urban energy system considering the uncertainty output of new energy and new energy vehicles. The uncertainty and operational flexibility of electric vehicles are taken into account at the planning level by using stochastic optimization method. The model considers the expansion and retirement of new energy units and various conversion devices in urban energy system, and ensures the achievement of carbon peaking and carbon reduction goals by imposing constraints on electric vehicles. The case results show that this model can effectively improve the economy and new energy consumption rate of urban energy system, and can meet the carbon reduction demand.

Optimal operation and control of smart energy systems

“…The eighth article, entitled “Model building of urban energy system and effect analysis of green low‐carbon transition under the background of carbon peaking and carbon neutrality” by Zhao et al, 8 discusses the energy system, taking into account the stochastic nature and fluctuation of renewable energies and electric vehicles. The model takes the expansion and decommissioning of electric vehicles and various conversion devices into account.…”
