A time based global optimization dispatching method

A time scale based global optimization dispatching method for a power distribution network, which is characterized in that:

• according to the value system and distribution network dispatching mode, performing a global distribution network optimization in accordance with a time scale, and performing long-term, mid-long-term, short-term, ultra-short term and real-time optimization of sub-goal adjustments, the method comprises the following steps,
• Step (1) establishing a global optimization target model for the power distribution network by developing a target hierarchy diagram for global optimization and building a model for the global optimization target;
• Step (2) dividing an overall objective of the model for the global grid optimization, into long-term, mid-long-term, short-term, ultra-short-term and real-time, five time scales, five optimization sub-goals;
• Step (3), according to the sub-goal of each optimization, together with distribution network dispatching policy set in the library, selecting a corresponding optimization strategy to optimize the sub-goal for each adjustment, to accomplish interactive collaborative dispatching among power, network and load.
