Abstract
The article present the results of studies aimed at emergency control (EC) methods development in power supply systems equipped with distributed generation plants. The main purpose of EC is ensuring postemergency mode dead-beat stability and high quality of dynamic transitions for electrical network load-shedding. Control actions were formed by changing the vector of controlled parameters along a path corresponding to the shortest distance to the hypersurface of the limit modes. The dynamic processes quality when implementing the control actions was ensured based on the special settings of excitation and frequency automatic regulators. Based on computer-aided modeling, it is shown that the effective introduction of a postemergency mode to the stability area can be performed based on generalized equations of the limit modes while using the start algorithm ensuring mode's entering the stability area's neighboring boundary. The implementation of the algorithms for concordant setting of regulators allows for the formation of a qualitative dynamic transition when performing load-shedding of distributed generation plants.
