Characteristics of air conditioners load and its impact on regional grid analysis

Air conditioners deserve special attention because they represent a significant part of the power system load. The modeling of air conditioners load is analyzed for simulation purposes, a simple methodology for modeling the effects of air conditioners load for short-term voltage stability analysis is presented and evaluated using a regional grid. Furthermore, the influence of the recover air conditioners load on the power system is analyzed. The result shows that the higher air conditioner ratio is, the heavier negative influence is on the network.
