Models of the individual components of the electric power system are described in Part I. The purpose of this chapter is to study mathematical relations between individual components to develop a model for the overall power system network, which is made of an interconnection of the various components.

This chapter describes the power flow analysis from both analytic and algorithmic viewpoints. Section 4.1 introduces the power flow problem through a simple example and clarifies the differences between power flow and circuit analysis. Section 4.2 provides a taxonomy of the power flow problem, while Section 4.3 presents the standard power flow ...

In the basic load flow problem, the so-called control variables are specified, permitting the feasibility of solution. We recall that the control variables consist of real power generation at all generation busses except the slack bus, and voltage magnitudes at all generation busses. The specification of these control variables is not arbitrary.

This chapter describes topological elements as well as standard shunt (i.e., connected to a single bus) devices for power flow analysis. The most important topological element is the bus, while standard devices are constant υΘ generators, PV generators, PQ generators, PQ loads and constant and switched shunt admittances.

This chapter reviews the power flow equations used in both power flow calculations and state estimation. The derivation of models of the main power network components is presented. Solvability conditions (“observability/controllability”) for the power flow problem are also discussed.
