基于蚁群算法的微电网多目标优化运行

Multi-objective optimization operation based on ant colony algorithm for micro-grid

为研究微电网的优化运行,建立了综合考虑微网运行总成本以及污染气体总排放量的多目标优化运行模型,将减少运行成本和污染气体的排放量作为子目标函数,通过引入污染物治理成本将多目标问题转化为单目标非线性问题。然后采用蚁群算法对单目标模型求解,结果表明该模型和算法有效、合理。

In order to study the optimization operation of micro- grid,this paper established a multi- objective optimal operation model. It is a model that considers both total cost of micro- grid operation and emissions of polluting gases,taking the reducing operating costs and the emissions of polluting gases as the sub- objective function.By this model,the multi- objective programming problem is reformulated into nonlinear mono- objective programming problem by using governance costs of pollutants. Then the ant colony algorithm was used to solve the mono-objective model. The results show that the proposed model and algorithm are effective and reasonable.
