一种改进的Tabu Search算法及其在区域电网无功优化中的应用

提出将改进的Tabu(禁忌)搜索算法用于区域电网无功电压优化控制问题的求解.首先根据已知的实际电网的历史数据获得可行的初始解,然后对区域电网采用改进的禁忌搜索方法进行无功优化.在求解的过程中,由于对Tabu表中所记录的"移动"采取"有条件地释放Tabu表中的记录"这一策略,可以使搜索有效地跳出局部极小值点,更好地找到最优解.通过IEEE-14节点算例验证了该算法的有效性.

Improved tabu search algorithm based reactive power optimization in regional power grid

The paper proposed an improved Tabu search algorithm for optimization of reactive power in regional power utilities.Firstly,the applicable initial solution is obtained according to the historical data in real systems.Thereafter,the improved Tabu Search algorithm is utilised to optimize reactive power.The strategy to release the records in tabu table conditionally for the moves recorded in tabu table is adopted during the process of searching the global solutions,which can escape from the local minimum and search the global solution more effectively.The simulations on IEEE-14 bus system prove its validity.
