Electric-carbon Coupling Planning Method for Distribution Grids in the Con-text of High Percentage of Distributed Photovoltaic Grid Integration
The state has implemented strengthened green certificates and carbon reduction policies,clarified the connection between power supply and carbon emissions,and electric carbon coupling has become an in-evitable trend.Under the background of carbon tariff policy implemented by EU,China's carbon tax may in-crease significantly,so a method that can accurately describe and evaluate the trend of carbon tax change is needed.Therefore,based on the calculation method of power carbon emission of distribution system,the plan-ning cost and carbon tax are included in the total planning cost,and the minimum planning investment of distribution system is taken as the objective function.The constraint conditions such as carbon emission factor,power flow constraint,node voltage constraint,branch current constraint and investment constraint are estab-lished,and an electric carbon coupling planning model of distribution system is constructed.The aim is to de-scribe the relationship between electricity consumption and carbon emissions.Based on the conditional value at risk(CVaR)theory,the electrocarbon coupling programming model is optimized,and a method to quantify car-bon tax fluctuations under extreme loss scenarios is given to predict the large changes of carbon tax.The IEEE 24-node system was used to simulate the model and the carbon tax fluctuation quantification method.The results show that the model can provide an electric carbon coupling planning scheme and can effectively evaluate the extreme changes of carbon tax.
