【Abstract】 The hybrid voltage control theory has been established to carry out the multi-objective optimal voltage control for power systems.To setup the hybrid voltage control system of the distribution grids,an index system is studied and presented in this work,which is used to evaluate the system performances and enables the event-driven control strategies.The proposed index system is so practical that it contains different indexes for the security,voltage quality and economy of the distribution grids,which are easy to be measured and calculated on-line.Since all these indexes are unified to satisfaction levels based on the fuzzy functions,the maximum satisfaction optimal method could be adopted to solve the multi-objective optimal problem raised by the multi-events situations.The case studies of a real distribution network shows that based on the proposed index system,the hybrid voltage control system can enhance the security,voltage quality and economy of the distribution grids effectively.更多还原
