Optimal Dispatching of Distribution Network Considering Inverter Air Conditioner Aggregation

The proportion of distributed energy resource (DER) in the distribution network has been increasing year by year to realize “carbon peaking and carbon neutrality goals”. However, new energy power generation is random and intermittent, and with the increasing peak-to-valley difference in loads, it is difficult to satisfy the peak shifting demand with only traditional power generation side resources. Therefore, it is essential to fully exploit the external characteristics of distributed energy sources on the user's side and engage them in distribution network optimization dispatching. In this paper, the inverter air conditioner on the user's side is modeled and aggregated. Based on the mathematical model, the regulation potential and external characteristic curves of the inverter air conditioner aggregation were evaluated and analyzed. The effectiveness of the proposed external characteristics of inverter air conditioner aggregation are verified in the IEEE 33-node distribution network model. It turns out that the aggregation of user-side inverter air conditioners can efficiently participate in distribution network optimization and improve distribution network reliability.
