Three-Objective Optimal Scheduling for Microgrids

A microgrid (Micro-Grid), also referred to as a micro-net, is an innovative network structure consisting of distributed generation sources, loads, energy storage systems, and control devices. It operates as an autonomous system capable of self-control, protection, and management, functioning either in grid-connected mode or independently as an isolated network. Compared to conventional large-scale power grids, microgrids organize multiple distributed energy resources and their associated loads into specific topological configurations, connecting to main grids through static switches. Algorithm Enhancement: Implementation often involves tri-objective optimization models considering economic dispatch, environmental impact, and reliability metrics. Code frameworks may utilize heuristic algorithms (e.g., NSGA-II) to handle nonlinear constraints, with energy management systems (EMS) executing real-time scheduling through predictive control loops. The development and expansion of microgrids significantly facilitate large-scale integration of distributed generation and renewable energy sources, enabling highly reliable multi-energy supply for diverse loads. This approach serves as an effective pathway toward active distribution networks, accelerating the transition from traditional grids to smart grids. Consequently, microgrid technology presents a promising and critical solution for future energy supply, ensuring reliability while promoting environmental protection and sustainable development.
