Chapter 4. Intelligentization of control systems for local electric power systems
Keywords:
Local electrical systems, autonomous mode, renewable energy sources, intelligent control systemSynopsis
With the increase in the power of renewable energy sources (RES) in power grids and the introduction of methods and means to compensate for the dependence of their generation on natural conditions, their role and significance in electrical power systems (EPS) is changing. RES are a real opportunity to decentralize electricity generation and provide power supply systems with a reliable source of energy. It has been shown that it is advisable to do this in the form of local electrical systems (LES), which operate in normal modes in parallel with the EPS as balancing groups, and in extreme cases are capable of operating in isolation in autonomous mode. To ensure the reliability and quality of electricity supply to consumers in LES, it is proposed to integrate RES and energy storage systems (ESS) in the form of separate microgrids (MG). To ensure the technical and economic efficiency of MGs, they are combined into an intelligent control system based on the principles of SMART Grid. This allows for more rational use of MG resources, effective interaction with the distribution network, and the use of ESS capabilities as a renewable energy reserve in the process of balancing the LES mode. The paper proposes a hierarchical structure of the intelligent LES system as one consisting of separate agents designed to respond to changing current LES states and form collective actions to ensure reliable power supply to consumers. Autonomous agents make management decisions and form a multi-agent system. Structured in this way, LES with smart grids can, during centralized power supply restrictions, not lose RES, but fully utilize their advantages together with energy accumulation and storage systems for reliable power supply to consumers.
