Limits on Power Injections for Security-Constrained Power Flows

摘要

A power system in steady-state is described by a set of nonlinear equations known as the power flow equations. The system has to be operated within the operating limits of the equipment. This is described by a set of inequality constraints, known as the security constraints. The steady-state security analysis problem is formulated as one of determining the existence of solutions to the power flow equations in the region defined by the security constraints. Explicit limits on the amount of power generation and load demand within which the system can be operated with all the security constraints satisfied are obtained. (ERA citation 06:028582)
