Load models for flat panel TVs

A realistic representation of power system loads has proven to be essential to ensure reliable and economic operation of a power system. Although the exact load model is nearly impossible to obtain, it is still possible to find a suitable load representation that can improve dynamic simulations. With the ever increasing development of technology, electric appliances and equipment behavior have changed. In particular, home electronics, such as televisions, are a good example of these changes not only for their cutting edge technology but also for their penetration into the system. Electronic loads tend to behave mostly as constant power with respect to voltage variations, which leads to issues of instability in the system. Therefore, this paper describes the necessity of updating the load models by analyzing their effects on the stability of the power system. Then, it introduces the importance of television as a contributor of electricity consumption. Finally, ZIP load models for televisions are developed as means of obtaining a better representation of these loads.
