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.
Highlights
With the development of society and waste management across the globe, Zero Waste City has become the goal of more and more countries or cities
Main purpose of the paper is to realize the optimal operation of waste disposal facilities with multienergy-system, which make large-scale reduction of city's waste in the most economical operating mode and improve the flexibility of power grid regulation
MODELLING The optimization analysis of Multi-energy Waste Disposal System (MEWDS) in this paper mainly considers the power flow
Summary
With the development of society and waste management across the globe, Zero Waste City has become the goal of more and more countries or cities. There is no previous research paper about the optimization model of urban waste disposal capacity and its energy supplement considering the coordinated operation of waste disposal facilities and multi-energy system. Main purpose of the paper is to realize the optimal operation of waste disposal facilities with multienergy-system, which make large-scale reduction of city's waste in the most economical operating mode and improve the flexibility of power grid regulation. The proposed MEWDS optimal model can get more economic benefits to reduce operating costs from energy supply and storage and waste reduction, and it will improve eco-environmental quality effectively.
