Modelling and Optimal Day-ahead Dispatch of District Energy Centre Considering Price Elasticity of Energy Load Demand
摘要
Abstract
As the energy market is being deregulated,the energy price,as a controllable resource,is expected to promote the optimized operation of multi-energy (such as electricity,gas,heat/cool) in the district energy centre (DEC).Based on the energy hub modelling method,the general linear modelling method of power balance equation in DEC is presented.In addition, after taking into account the price elasticity of energy load demand,piecewise linearization modeling of energy load demand is conducted,and the description of piecewise linear function is unified by introducing a 0-1 logic variable and several linear constraints.Further,aiming at DEC net revenue maximization,the mixed integral quadratic programming model for optimal day-ahead dispatch of DEC is developed,in which the controllability of energy price is taken into consideration,and CPLEX called from GAMS is used for solution.Finally,with a case study on microgrid-type DEC,the proposed modeling method is verified,and the influences of control of energy price,different price elasticity and prediction error of new energy on the dispatch results are analyzed.The results show that full use of load price elasticity will help reduce load variance and peak-valley difference,and deep the optimization potential of DEC,while maximize the DEC revenue.关键词
