PROJECT TITLE :

Metrics-Driven Information Governance

ABSTRACT:

Information framework of optimal reactive power dispatch (ORPD) and the essential characteristics of coordinated reactive power optimization (RPO) in multi-area giant-scale power systems are introduced during this paper. We take into account that the change of optimal solutions (management settings) cannot be captured by simply using an equality constraint of the boundary values as which the voltages at boundary buses and power flows in tie lines are cited. While many previous strategies were proposed by using amendment of the boundary values to judge the amendment of optimal solutions, that would possibly result in failure in convergence, this paper puts forward a coordination strategy according to the correspondence between optimal solutions and boundary values based mostly on a probing mechanism. This method is applied to a 472-bus power system; the simulation results show that the RPO scheme primarily based on this strategy has robust convergence capability and high efficiency. Moreover, the proposed coordination strategy permits the transmission system operators (TSOs) to settle on objective function and optimization algorithm independently.
