Abstract:This thesis involves the development of network and load models for power system analysis. Traditional power system models consist of detailed generator models and simple network and load models. In the past this has been acceptable as these models captured observed phenomena. These models do not sufficiently describe the system under heavily loaded conditions; in fact, the mathematical equations may not exhibit a solution. This is unacceptable. The problem is that the form of traditional load models is chosen for convenience and is not based on actual load dynamics. In this thesis, network and load models are presented that capture important frequency and voltage dependencies. Conditions on a common class of static load models are given to ensure that the power system algebraic equations will exhibit a solution. An induction motor model is used to justify dynamic load models that appear in the literature and to develop new models. These models are important because they are based on physical motor characteristics. Steady-state, transient, and structural stability studies are performed to examine the effects of different static and induction motor loads.
