Cleaning model of a spot electric energy market considering flexible ramping auxiliary services and wind curtailment penalty
摘要
Abstract
A cleaning model of a spot electric energy market considering modified flexible ramping auxiliary service and wind curtailment penalty is presented to solve issues such as insufficient system ramping capacity caused by wind power uncertainty and high total operating costs caused by a high penetration of wind power.First,a modified flexible ramping auxiliary service is proposed.This is done by analyzing the flexible ramping speed constraints that a single-unit needs to meet during output,startup and shutdown processes,and the flexible ramping ability constraints that the system needs to meet because of net load fluctuations.Secondly,an objective function that takes into account the modified flexible ramping auxiliary service and wind curtailment penalty is established.It uses output plans and the status of generators as decision variables.Finally,two examples are given to verify the effectiveness of the proposed cleaning model through in-depth analysis from different perspectives such as wind power forecasting error,penetration ratio,and curtailment penalty cost.The simulation results show that the presented model not only improves system flexibility and economy of system operation,but also enhances the consumptive ability of a high proportion of wind power.关键词
