Multi-objective Dynamic Unit Commitment Optimization for Energy-saving and Emission Reduction with Wind Power

摘要

As a clean energy, wind power is massively utilized in net recent years, which significantly reduced the pollution emission created from unit. This article referred to the concept of energy-saving and emission reducing; built a multiple objective function with represent of the emission of CO_2& SO_2,the coal-fired from units and the lowest unit fees of commitment; Proposed a algorithm to improving NSGA-□(Non-dominated Sorting Genetic Algorithm-II) for the dynamic characteristics, consider of some constraint conditions such as the shortest operation and fault time and climbing etc.; Optimized and commitment discrete magnitude and Load distribution continuous quantity with the double-optimization strategy; Introduced the fuzzy satisfaction-maximizing method to reaching a decision for Pareto solution and also nested into each dynamic solution; Through simulation for 10 units of wind power, the result show that this method is an effective way to optimize the Mul-ti-objective unit commitment modeling in wind power integrated system with Mixed-integer variable.
