An investigation of the solution of the problem of optimizing the operating conditions of electrical networks in voltage and reactive power using the method of sequential linearization and linear programming

摘要

Algorithms for solving the problem of optimizing the operating conditions of an electrical network in voltage and reactive power using linear programming methods are proposed. The approach proposed employs sequential linearization of the objective function as the total active power losses and constraints imposed on dependent variables in form of the equations of steady-state operating conditions of the electrical network. The effect of the step on the solution of the problem using the approximating programming method is analysed. The workability and applicability of the algorithms is verified on examples of 6-, 20- and 96-node circuits of electrical networks.
