Abstract
With the development of integrated energy systems,natural gas network and microgrid will be deeply cou?pled. Therefore,the comprehensive utilization level of multiple energies will be improved by the time-of-use(TOU) pricing of natural gas and electricity,and the allocation of energy resources will be optimized. In this paper,an optimal model of combined gas-electricity peak-valley TOU pricing,which considers the integrated demand response of natural gas and electricity,together with three price linkages of natural gas,power generation,and power supply,is estab?lished. The minimum average energy cost per unit electricity is taken as the objective function of this model,and the benefits of all participants,which should not be damaged after implementing the combined gas-electricity TOU pricing, are taken as constraints. Two operation modes,i.e.,gas-electricity peak overlap and peak shifting,are adopted in the simulation. Simulation results show that both modes have the optimal TOU prices of natural gas and electricity;the opti?mal combined TOU prices differ more obviously in the peak shifting mode than in the peak overlap mode,and the corre?sponding effect of peak load shifting and energy-saving efficiency are better;the effectiveness of the proposed model is verified from the aspects of technical and economic efficiencies,thus a reasonable pricing under the coupling between natural gas network and power grid can be realized.关键词
