Intelligent Optimal Scheduling Of CCHP System Considering P2G,Demand Response And Incentive Policies

With the global energy shortage,the Combined Cooling,Heating and Power microgrid is widely used in production with the advantages of efficient renewable energy utilization,reliable power supply capacity and less environmental pollution.Therefore,it is important for the CCHP system can be reasonably dispatched and optimized.Aiming at the problems of low power generation efficiency,large energy loss,and abandonment of the coexistence of Wind power and Solar power the current CCHP system,this paper adds Power to Gas,Energy Storage systems,Demand Response,and Incentive Policies to the system to study the improvement of renewable energy consumption,and the way to reduce energy loss and get the most revenue.The paper builds a CCHP system model which includes Wind Turbine,Photo Voltaic,P2G systems,Gas Turbine,Gas Boiler,Electric Boiler,Waste Heat Recovery Devices,Absorption Chiller,Electric Chiller,Solid Oxide Fuel Cell,Ice Storage Tank,and Heat Storage Tank is a Cost-Benefit model constructed,taking the annual maximum net revenue of the CCHP system as the objective functionCombining the jointed Wind power,Photo Voltaic power and user-side load of cooling,heating,electricity and gas on typical days in spring/autumn,summer and winter in a certain area in Northwest China.The unit dispatch model are simulated and analyzed.Time of use tariff,and gas prices are also taken into account.In 4 case under island and grid-connected modes using improved Particle Swarm Optimization.It is found that under the island mode,the Energy Storage system can promote the consumption of renewable energy.Case 3 has the maximum net revenue and it is 2.8 times that of the Case 1.In the grid-connected mode,the maximum annual net income of Case 4 is 1.405 times that of Case 1,and the annual utilization rate of renewable energy is increased by 12.36%.In the paper system,three incentive policies of Demand Response and Feed tariff,carbon trading market,and the penalties of wind curtailment are considered,and a new cost-benefit model is constructed.Simulation analysis shows that in the grid-connected mode.The optimal dispatching scheme is Case 4,and its maximum annual net income is 1.423 times that of Case 1,and the annual utilization rate of renewable energy is increased by 13.27%.Comparing the optimal dispatch plan before and after considering the Demand Response and Incentive Policies,the annual maximum net income of Case 4 is increased by 207,700 yuan,an increase of 23.39%,and the annual utilization rate of renewable energy is increased by 3.52%.P2G system and Energy Storage Systems can promote the consumption of renewable energy,reduce greenhouse gas emissions,and increase the environmental benefits of the system.Demand Response and Incentive Policies enable the generators to obtain the largest annual net income.
