Capacity configuration optimization for the CCHP system considering integrated de-mand response
摘要
Abstract
In the context of the'carbon peak and carbon neutrality'goals,the peak-valley difference in energy sys-tems,primarily dominated by new energy sources,becomes increasingly pronounced.Leveraging the complemen-tary characteristics of a combined cooling,heat,and power(CCHP)system,users can respond to time-of-use(ToU)tariff by flexibly switching energy sources to meet integrated demand response.Addressing scenarios where buildings simultaneously demand cooling,heat,and power,the study designs an integrated demand response strat-egy incorporating waste heat utilization and prime mover shutdown during valley periods.The research investigates the optimization of key equipment capacities and cost variations for the CCHP system under different operational strategies.The findings indicate that the strategy of economically utilizing surplus energy effectively reduces the overall system operational costs.This approach is suitable for situations where all three loads(cooling,heat,and power)coexist,especially in scenarios where there is a significant cost disparity between natural gas heating and electric refrigeration.On the other hand,the strategy of shutdown during valley periods is applicable when the equivalent generation cost of natural gas falls between peak and valley electricity prices that vary substantially.关键词
