Scheduling Strategy and Economic Operation Optimization for Micro-Grids

The micro grid system has something different from the traditional power grid. That is the power grid real- izes the balance of system based on load forecast, adjusting the controllable generators. While the generation units and load in microgrid have strong volatility and randomness. This paper bases on a microgrid with solar system, wind power, energy storage, load and power grid, aims at the problem that how to balance the random load and generator, studies the two operation state of the microgrid, establishes the scheduling strategy, operation optimization method and operation objectives. Analysis and verify the correctness and effectiveness of the proposed scheduling model, scheduling strategy, optimized objectives and optimization algorithm with an example.
