Abstract

This paper presents a methodology to calculate an optimal solution of equilibrium to differential algebraic equations for power system. It applies a nonlinear interior point method to solve the optimization formulation, which includes dynamic equations representing two-axis synchronous generator models with AVR and speed governing control, algebraic equations, and steady-state nonlinear loads. The solution process employs a decoupled block factorization. This makes it possible to pre-serve the structure in conventional Newton-type optimal power flow. Equilibrium Optimization (EOPT) tool is useful for diverse purposes in power system analysis and control. In case study, an example is given applying EOPT to 6-bus test system.
