Development of Dispatch Control Facilities: A Technique for Identifying the Current Limitation Factor of Transmitted Active Power

The effect of allowable exchange capacity actualization according to the Guidelines for the Power Systems Stability has been determined The Onda - Kondopoga area was used as an example of the high loaded controlled areas. Requirements for the relevance of operational information, actual values of control actions and balance sheet situation are raised in addition to changes in regulatory documentation. New dependencies are identified in determining the maximum allowable exchange power values. This complicates the task of identifying the current limitation factor by the dispatch office personnel at the stage of electric power mode managing. The need to develop new and refine existing tools for monitoring the electric power mode has been identified in this research. The authors have developed a technique to identify the limiting factor of allowable power flow area. The developed method allows reducing the probability of errors in the identification of the limiting factor of allowable active power flow area. It facilitates rapid decision-making in the management of the electric power mode thus directly affecting the main technological activities of dispatch control centers.
