RESERVE OPTIMIZATION METHOD AND APPARATUS BASED ON SUPPORT OUTAGE EVENT CONSTRAINED UNIT COMMITMENT

摘要

A reserve optimization method and apparatus based on a support outage event constrained unit commitment. The method includes the following steps: step 1: running a basic unit commitment reserve optimization model to obtain a basic unit commitment dispatch resu step 2: establishing a committed capacity outage probability table (CCOPT) based on the dispatch result, calculating the loss of load probability (LOLP), and identifying the marginal events therefrom; and step 3: adding linear constraints corresponding to the marginal events to the reserve optimization model to obtain a new dispatch result, and returning to step 2 till the result meets the LOLP requirements. Multiple compromises in the problem are considered, and the LOLP constraint is simplified such that the model can be accurately and efficiently solved.
