This thesis presents research results on the effects of tap changing dynamic modeling on power system mid-to-long term voltage behavior. The modeling of tap changing dynamics in voltage stability studies is first addressed. The dynamic operation of an on-load-tap—changing transformer is represented by a highly nonlinear, discrete and time—delay embedded model, which is suitable to mid-to—long term voltage stability studies. Different discrete tap models and their continuous approximations with respect to time and tap position are introduced. The initial emphasis is on studying the i

As California continues to integrate more renewable energy into its electrical system, the state has experienced a corresponding rise in photovoltaic system installations. PV arrays are a unique source of power generation in that they are affected by the location of the sun, shading, and temperature changes. These characteristics make solar one of the most highly variable forms of renewable energy. In order to improve solar power’s consistency, PV systems require a supplemental source of power.

To ensure that operators make the correct simulation-based decisions, the power system models have to be validated continuously. This thesis investigates power system modeling, id
