Research on Optimal Dispatch with Source-Load Coordination for Micro-energy Grid Based on Energy-Carbon Coupling Model
摘要
Abstract
At present,the low-carbon dispatch of the integrated energy system focuses on the means of carbon reduction at the source side,while ignoring the low-carbon potential of the load side and the ability of carbon reduction for source-load coordination.Taking the micro energy grid coupled with power,heat and gas as the research object,an optimal dispatch method with source-load coordination of heterogeneous energy flow system based on energy-carbon coupling model is proposed,and a two-stage optimal dispatch framework of day-ahead and intra-day based on the process of source-load coordination is built.In the source side,the combined heat and power(CHP)units with adjustable heat-to-power ratio coupling with power-to-heat equipment are used for energy supply,and the dynamic carbon emission characteristic of each unit in the energy station is considered;In the grid side,the energy-carbon coupling model of power and heat energy is established by using the carbon emission flow theory,and the obtained distribution of carbon intensity is transferred to the load side;Based on this carbon information and considering the impact of time-sharing energy price,the load side guides the load to adjust behaviors of energy consumption in real time to respond to low-carbon demand,and feeds back the updated load to the source side to re-optimize the output of each unit,so as to realize the process of source-load coordination.The effectiveness of the proposed method is verified by analyzing the micro energy grid composed of the improved IEEE 33-node power grid and the Barry Island 32-node heat grid.关键词
