An OOP based real time reactive power control algorithm for large power systems

Voltage and reactive power control is essential for secure and optimal real time operation of power systems. The problem is of special significance in case of stressed power systems, where bad reactive power management can lead to excessive MW loss in the system. This can cause reduction in load bus voltages and active load, changes in system frequency and voltage stability problem, all being detrimental to system operation. This paper proposes an object oriented programming (OOP) based reactive power/voltage control algorithm for large scale power systems which tries to improve system voltage with curtailed number and reduced controller movements, so that the decisions can be implemented in real time. The algorithm is specially suitable for use in energy control centers
