Abstract

With the constant expansion of Yunnan power grid, in current dispatching Automatic generation Control (AGC) mode, the use effect of small and medium-sized hydropower resources in the unified dispatching was not ideal. By building zoning control model artificially, the control targets and their coordinated relationship between main area and sub-areas are explicitly pointed out .The zoning and layered control mode of AGC between provincial dispatching and regional dispatching is put forward. Analysis and comparison are also made of the “independent zoning and layered control mode” and “coordinated zoning and layered control mode”, and then their existing problems are pointed out. The research can provide the foundation of further study on AGC coordinated control strategies between provincial dispatching and regional dispatching, which can realize single goal and multi-objects of AGC coordinated control in the power grid.
