Suppressing AC Tie-line Stochastic Power Fluctuation by HVDC Power Modulation Control
摘要
Abstract
The stochastic power fluctuation on an AC tie-lie of two-area interconnected power systems under normal operating conditions reduces the tie-lie’s transmission capacity and threatens the secure operation of equipment. Reducing and suppressing the AC tie-line power fluctuation becomes one of the most important issues to be solved in operations. Suppressing AC tie-line stochastic power fluctuation by high voltage direct current (HVDC) power modulation control was proposed. A surplus or shortage of power in an AC area could be absorbed or compensated rapidly by its connected HVDC power modulation, so the power fluctuation on the AC tie-lie could be reduced or suppressed. The HVDC modulation performance index considering power regulation ratio was presented, and the optimal gain of the HVDC modulation controller was solved by an improved particle swarm optimization (PSO) algorithm. Thus, the HVDC transmission line could share the stochastic power fluctuation partially or totally with the AC tie-line. Cases studies on the North China and Central China interconnected power system show that HVDC power modulation provides an effective way to reduce or suppress the stochastic power fluctuation on the ultra-high voltage tie-line.关键词
