The integration of large-scale wind and photovoltaic power into modern grids leads to an imbalance between the supply demand for resources system, where this threatens safety stable operation grid. traditional mode grid dispatch capability regulation conventional thermal units cannot satisfy demands connection renewable energy, system requires compensation coordinated flexible sources. In light problem, paper establishes a model quantify uncertainty in forecasted outputs power. This is used develop forecasts output several groups scenarios, predictions with best complementarity are selected as typical set scenarios by means their generation, reduction, combination. By taking full advantage rates concentrating solar (CSP), power, CSP, established number combinations scenarios. influence on examined, different modes formulated through simulations analyze superiority strategy proposed terms abandoned quantity, cost dispatch.
