Abstract：Building anew power system with new energy as the main body is the hub platform for the“dual carbon”goal，buttheinstabilityof new energygeneration brings challengessuch aspeak shaving and lack of flexibilityto thepower system.To effectively balance theeconomyandsafetyof thesystem，the following stepsare taken.Firstly，the improved Worst Condition Value atRisk（WCVaR）is introduced to quantitatively evaluate the potential risks brought by theuncertaintyof new energy output.Secondly，anincentive strategy is introduced to balancethe electricity load and optimize and upgrade the peak shaving carbon capture of thermal power units， enhancing peak shaving capacityand new energy consumption level，and alleviating the excessvecarbon emissions caused by deep peak shaving of thermal power units.Thirdly，a low-carbon economic dispatch model is established withthegoal ofachieving comprehensiveoptimizationof systemoperationcostsandoperationrisks.Finaly，the effectiveness of theproposed model isverified through experimental simulations.

Key words：new power system; deep peaking; improved WCVaR; low-carbon economic dispatching
