摘要
Abstract
Two methods usually utilized in security correction of generation scheduling, namely equal and opposite quantities in pairs and linear programming, are compared. The linear programming probably has no solution because all its constraints are hard ones. In applications, when out-of-limit cannot be thoroughly eliminated, for decision-making it is necessary to give a solution that can mitigate the extent of out-of-limit. The features of both objective function and constraints in traditional security correction model are analyzed, and based on the principle in perturbation theory the deviation variable and penalty function are led in as perturbations to construct an optimization model with soft constraints to solve the trouble that the model with hard constraints is unsolvable as for traditional linear programming. The proposed model is simple and general, and when the out-of-limit is eliminable the respective solutions by the proposed model and the traditional one are the same; when the out-of-limit is indelible, the proposed model can offer a solution with mitigated extent of out-of-limit. Actual application in a certain provincial dispatching center verifies the effectiveness of the proposed model.关键词
