Urban waste disposal capacity and its energy supply performance optimal model based on multi-energy system coordinated operation

Abstract

In the world with Zero Waste City and Energy Internet construction is promoting to meet waste reduction and power grid regulation flexibility improvement. Based on the waste stockpile and disposal demands, the waste disposal facilities multi-time scale model of energy supply and demand is proposed. On these premises, This paper presents the Multi-energy Waste Disposal System (MEWDS) topology and its optimal model based on coordinated operation of multi-energy system and waste disposal facilities to maximize economic benefits. Through simulation, the case studies are performed for the waste stockpile and multi-energy operation data of a Chinese city from different waste disposal scenarios to demonstrate. The proposed MEWDS optimal model can make the waste reduced and the economic benefits best. Meanwhile, it can also improve the flexibility of power grid regulation effectively.
