Abstract
The program of the proposed project addresses the development of automatic voltage security analyses using a new approach to the voltage stability assessment via critical paths in the power system. The approach is not based on matrix methods and utilizes only information on the power system configuration and its measured data of power flow and bus voltages. A new voltage stability index will be formed comprising the path stability index and reactive power index. The new integrated index will be easier to understand for the operators in the control center. The index will be exploited for identification of the most endangered buses. The critical path concept shall be exploited for labeling of electric energy paths in the network, which will in turn enable calculation of cost of its transmission.
The procedures for estimation of the ready reserve and its optimal location will be developed for a power system or the interconnection. The search for new methods of estimating the critical states and assessing adequate measures for them will be carried out, including the protection against the voltage collapse. For that purpose, the secondary voltage and reactive power control will be investigated with the methods of artificial intelligence, which enables development of local, decentralized secondary voltage controllers.
