This paper presents a new evaluation model of wind-Photovoltaic (PV)-thermal-pumped storage integration system considering carbon emission. The model is constructed on the basis of comprehensively considering the construction cost, operation cost, start-up and shutdown cost of the unit, wind abandonment rate, PV abandonment rate and carbon emission cost, and fully utilizing the power curtailments of wind and PV. It analyzes the electric energy benefit and low-carbon economy in three different operation modes including wind-PV-thermal-pumped storage, wind-PV-thermal and thermal under the same load. The effectiveness and rationality of the evaluation method are verified by a simulation example. Combined with the dynamic carbon price, the carbon economy of three different operation modes is analyzed. The analysis results show that wind-PV-thermal-pumped storage integration system has the best electric energy benefit and carbon economy, and with the increase of carbon price, it has more development prospects.
