High level functions have been implemented in the EEF dispatching center as decision tools for the system operation staff. A real time security analysis software has been in service since May 1986. The software makes use of novel solutions for HV network operation problems. The architecture of the high level decision functions, the data base structure, the analytical functions (state estimation, observability, load-flow, contingency analysis) and the user friendly man/machine interface are described and dis

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 sy

This work describes the development of a fuzzy logic based control system capable of governing multiple thyristor-controlled series capacitors (TCSCs). The main purpose of the presented coordinated control system is the improvement of active power flow control in a power system. The proposed control strategy is quite simple; therefore it does not require intensive computations on on-line computers. The control system has been designed as a real time tool constantly monitoring power flows and generating appr
