In this paper, a new method based on modal analysis and CPF method devoting to designing of generation adjusting plan which can alleviate stressful voltage condition considering energy saving is proposed. The voltage stability condition has relation with the generation and load distribution modes, usually only adjustment of load distribution modes has been noticed when there is a need to alleviate stressful voltage condition. Noticing that properly modification of the generation mode under stressful voltage stability condition can also reduce the power loss of power system and enlarge the voltage stability margin, a fast generation adjusting strategy designing algorithm is proposed. In the mean time, coal consumption of each generator is also considered. Participation elements is employed in this method to select the generators which are effective in adjusting process, continuous power flow calculation algorithm is used to trace the variation of power loss in power system. The simulation result on IEEE 39 system show that the method proposed by this paper can modify the voltage stability condition and enlarge stability margin to certain extent.
