In this paper, the concept of end-user driven micro grid is introduced and an economic dispatch framework is proposed for optimal power and battery scheduling of such a micro grid. The main advantage is that unlike other centralized approaches reported in the literature, the proposed architecture provides end-user flexibility, optimally manages the battery minimizing the power required from the grid and at the same time ensures grid level reliability. The proposed optimal scheduling is first

Then the architecture is compared with one of the existing centralized optimization approaches. To demonstrate the applicability and scalability, the architecture is further evaluated on a modified IEEE 33 bus distribution feeder including multiple micro grids suitable for real-time implementation. The test results indicate that the approach is optimal, scalable, feasible, improves feeder reliability, and provides maximum utilization of the PV arrays. Index Terms-Battery power dispatch, economic dispatch, grid connected end-user driven micro grid, optimal scheduling, quadratic programming.
