The dispatch center’s role in the power grid operation and control.

The power grid consists of the production, transmission, and distribution system. Each of them, and particularly the transmission system plays a specific and significant role in the reliability and safety of the power grid. Compliably with the technological requirements and economic development trends, the power systems are upgraded and modernized in terms of their structuring, management and operation. Because of the interconnection between these systems and their role in a safe and reliable operation, their management and coordination are very specific and complex task. The primary task of the power Dispatch Center of the power transmission system is assuring the energy balance between the power production, and consumption, import and export of the active power and synchronous frequency. The dispatch center controls the active power flow and other electrical parameters and coordinate power generation and integration of renewable resources, and safety and reliability of power components (lines, transformers, substations). It coordinates the interconnected operation of power transmission systems in the synchronous area (tie lines), electricity market, and contingencies according to the set levels. It manages faults in power transmission system components, coordinates the power distribution system, and ensures an optimal, and economic power dispatch. [ABSTRACT FROM AUTHOR]
