摘要:the current major restructuring of the electricity market and the advances of new technology add new complexities in the power system applications software, particularly optimization. Minimization of the impact of a transaction on unrelated third party facilities or maximization of the power transfer between utilities needs now to be formulated as new constraints or objective functions. The dispatch and control of generating units, the taps of regulating transformers, mechanically switched capacitors and reactors have been the primary means available for controlling power flows over the years. However, certain applications require frequent operations that result in a rapid wearing out of the switching equipment. The inadequate line flow control may result in overloaded parts of the networks, while other parts are loaded far below their power carrying capacity. Therefore, the demands for flexibility in power flow control are growing continuously. The FACTS relying on thyristors have high speed switching capability that allows for rapid readjustment of line power flows in response to various contingencies. Installation of FACTS devices on key locations in a meshed network changes the effective reactance of the parallel paths and consequently the way that power divides among them. This paper proposes study of various FACTS DEVICES that can be installed. FACTS DEVICES model is incorporated into a Newton-Raphson algorithm to perform load flow analysis. Proposed algorithm is tested on IEEE 30 bus power system for optimal allocation of STATCOM and results are presented
