Abstract
The traditional combined cooling heating and power (CCHP) system researches mainly focus on its operation optimization,and lesson the siting and sizing of distributed generation (DG) in the system.The demand response (DR)based on price and incentive is not taken into account in the process.Based on the multi-energy complementary characteristics of CCHP system,this paper puts forward the siting and sizing model of distributed power with considering price and incentive based DR,which takes distributed power access nodes and access capacity as variables.Firstly,we establish the thermo-electric coupling operation model for CCHP system.Secondly,we propose the pricing method of unit power compensation with interruptible load,comprehensively considering load reduction,interruption duration and interrupt time factor.Then,by analyzing the DR cost in the objective function,the planning goal is more comprehensive and the investment is saved.In addition,based on the consideration of incentive and price-based DR,an improved price elasticity coefficient is defined with considering the influence of electric price,gas price and the compensating price of unit power with interruptible load,which is used to correct the load forecast.At last,the planning model is solved by the neighborhood redispatch particle swarm optimization algorithm (NR-PSO).And through the simulation analysis of a 13-node integrated park system,the validity of the proposed model and method is verified.关键词
