Optimal dispatch of nearly-zero carbon integrated energy system considering waste incineration plant-carbon capture system and market mechanisms

Abstract

Considering the waste incineration plant-carbon capture (WIP-CC) system and market mechanisms, the optimal dispatching strategy of nearly-zero carbon integrated energy system (NZC-IES) is proposed. The incineration of large amounts of Municipal Solid Waste can result in significant carbon emission and air pollution. However, lack of consideration of mechanisms for carbon processing and environmental protection will prevent the development of NZC-IES. Accordingly, a novel mixed integer nonlinear mathematical model, NZC-IES, is established that minimizes the total cost and controls carbon emission and air pollution. Unlike previous studies of optimal dispatching for WIP-CC system, the climate and health costs of WIP and the social costs of energy sources for CC are considered. A model of adjustable thermoelectric ratios for WIP and a model for CC with the storage tanks are established to enhance the flexibility of the thermoelectric output. Also, demand response model and ladder-type carbon trading model are developed to serve for NZC-IES. Case studies reveal that the proposed optimal dispatching strategy can realize the waste to energy utilization and low-carbon emission with economic performance.
