A bi-level distributed optimization approach for weakly interconnected networked microgrids

A bi-level distributed optimization for networked micro-grids with weak interconnection is presented. In the upper-level, the scheduling model of the networked micro-grids is optimized by the alternating direction method of multipliers (ADMM) to reduce the operation cost. The lower-level internal optimization model of micro-grid based on cooperative game is solved by particle swarm optimization (PSO) to minimize the cost. This optimization approach can enhance the economy and reliability of networked micro-grids, achieving effective cooperative control and management.
