Calculation of the Potential for Electric Energy Substitution in the Construction Field Considering the Carrying Capacity of the Distribution Network
摘要
Abstract
As clean energy technologies continue to advance,various electric energy substitution solutions have emerged in the construction sector.With the large-scale integration of electric energy substitution loads,assessing the load-carrying capacity of the distribution network for safe operation is crucial for distribution network planning.Firstly,three typical electric energy substitution technologies are selected in the construction sector:electric boilers,heat pumps,and air conditioners,and constructs a full-cycle economic assessment model considering the entire lifecycle of the equipment.Next,using an integrated energy system as the research object,the equipment and loads are modeled with the objective function of maximizing the number of electric energy substitution devices that the distribution network can accommodate.The model takes into account constraints related to the safe and stable operation of the distribution network,equipment output,as well as economic and policy factors.An electric energy substitution potential calculation model is then established and subsequently reformulated as a second-order cone programming model using second-order cone relaxation techniques.Finally,by simulating the IEEE 33-bus test case,a quantitative evaluation of the load-carrying capacity of the distribution network is achieved,demonstrating that,under policy support,electric energy substitution devices that consider economic factors have a broader development potential.关键词
