Decentralized Emergency Control of AC Power Grid Modes with Distributed Generation

Large-scale development of small-scale generation, and facilities based on this, with their integration into existing distribution networks, qualitatively change the modes tasks network management transform previously passive electric networks active ones. Features parameters insufficient observability manageability in centralized determine need to use a decentralized multi-agent control such networks. First all, this applies emergency management, which includes automatic restoration integrity normal operation network. This paper presents set specialized methods for power grid results study effectiveness mathematical physical models that confirm feasibility using recovery management. In particular, includes: method proactively balanced separation energy districts along one priori fixed cross-sections event disturbances transition island mode, two-stage mode synchronization parts remote switches. case parts, it is proposed special excitation speed generators create conditions successful reclosing devices detection. It essential small generation reject concept ensuring reliability supply through maintaining favor an emergency-balanced breakdown areas subsequent integrity. To conduct research model, prototype distributed system automation has been developed does not data transmission tools, ensures its high cybersecurity
