Design of a Terminal Sliding Mode Controller for Distributed Generation Systems Based on Multi-Agent Systems

Distributed generation is a new trend in electric power production. These units are placed in substations and distribution feeders near loads, and are used either independently or in parallel with electrical grids. The use of "intelligent agents" refers to agents that must operate robustly in open, unpredictable environments where significant changes may occur. In this paper, wind turbines and photovoltaic systems are considered as distributed generation agents, with each of these elements treated as an individual agent. Given the heterogeneity of these agents, the system is considered heterogeneous, complicating problem-solving. To address this issue and convert it into a homogeneous problem, it is assumed that identical agents have separate leaders, and if all agents are synchronized, the heterogeneous problem can be effectively treated as a homogeneous one. Following the leader is achieved using a terminal sliding mode controller, with the primary advantages of this method being overall system stability, finite-time convergence, and agent synchronization.
