Abstract

This work describes a development of a control system and control strategies capable of governing multiple flexible AC transmission system (FACTS) devices. The main purposes of the presented coordinated control system are to remove overloads and to achieve specified power flows in transmission lines of a power system in the normal and N-1 steady-state operational modes. Proposed control strategies are based on heuristic rules; therefore they do not require intensive computations. A prototype of a control system has been designed as a real time tool constantly monitoring power flows and generating appropriate control signals to each FACTS device in order to maintain acceptable power flow levels. It has been interfaced with load flow software to test its effectiveness through non-linear simulations using the 380/220 kV Swiss power system as the study case. The results obtained are presented

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.

AC power

In an electric circuit, instantaneous power is the time rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. Its SI unit is the watt. The portion of instantaneous power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as instantaneous active power, and its time average is known as active power or real power.

Electric power transmission

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid.
