Abstract

Linear programming application for optimal active power flow under constraints shows very good results, without causing particular problems. However, the same technique is more difficult to apply to reactive power optimization, due to the nonlinearity of relations between the reactive power injections and the voltages. An iterative and decoupled method, based on optimization of injected reactive currents, for minimizing the production cost and active losses under bus voltage and branch flow constraints, is proposed. An illustrative example applied to an actual 220/125 kV network shows the possibilities, the efficiency and the limits of this method

Power-flow study

In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as voltages, voltage angles, real power and reactive power. It analyzes the power systems in normal steady-state operation. Power-flow or load-flow studies are important for planning future expansion of power systems as well as in determining the best operation of existing systems.

Linear programming

Linear programming (LP), also called linear optimization, is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships. Linear programming is a special case of mathematical programming (also known as mathematical optimization). More formally, linear programming is a technique for the optimization of a linear objective function, subject to linear equality and linear inequality constraints.

Power system simulation

Electrical power system simulation involves power system modeling and network simulation in order to analyze electrical power systems using design/offline or real-time data. Power system simulation software's are a class of computer simulation programs that focus on the operation of electrical power systems. These types of computer programs are used in a wide range of planning and operational situations for electric power systems.
