实时平衡市场是保证电网在市场环境下安全经济运行的关键。实时平衡市场在国内还处于起步阶段,与此相关的理论研究和实践相对较少。文中提出了实时平衡交易模型并给出基于内点法的求解算法。实际工程应用表明,这种求解方法具有计算速度快、收敛性好、鲁棒性强等优点。该算法已经应用于河南电力市场。 Real-time balance of the market is to ensure that the power grid in the market environment, the key to safe and economic operation. The real-time equilibrium market is still in its infancy in China, and there are relatively few theoretical researches and practices related to this. In this paper, a real-time equilibrium trading model is proposed and a solution algorithm based on interior point method is given. The practical engineering application shows that this method has the advantages of fast calculation, good convergence and strong robustness. The algorithm has been applied to Henan power market.
