Multilevel micro-electric network control method based on four-dimensional energy management space

Abstract

The invention provides a multilevel micro-electric network control method based on four-dimensional energy management space. A micro-electric network system comprises multilevel micro-electric networks and distributed power sources. The multilevel micro-electric network control method comprises the steps as follows: (1) establishing a four-dimensional energy management space model; (2) establishing control strategy bases corresponding to the four-dimensional energy management space model; and (3) executing the energy management and control of the micro-electric system. Through multi-dimensional combination, the multilevel distributed power source / micro-electric network energy optimum management problem is effectively solved under the conditions of different modes, different time sequences and multiple constraint; and meanwhile, through integrated restraint, a theory can be flexibly applied to the operation control of a unipolar micro-network / single device. In practical application, the number of the layer / level of each dimension can be freely and flexibly selected as required, influence factors under various conditions and restraint can be comprehensively considered, and corresponding control strategy bases can be systematically deduced and applied in real time, so that the economic dispatch and the optimum operation of the multilevel distributed power source / micro-electric network networked system are ensured.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a multi-level micro-grid control method based on a four-dimensional energy management space. Background technique [0002] In recent years, with the deterioration of the environment and the scarcity of non-renewable energy sources, renewable clean energy generation technologies represented by wind energy and solar energy have developed rapidly. Among them, the flexible and decentralized connection of small wind power generation and photovoltaic power generation to the user-side distribution network can improve the reliability of local power supply, reduce transmission loss, improve the utilization rate of primary energy and reduce exhaust gas emissions. The wind and photovoltaic power generation systems connected to the distribution network in this way are collectively referred to as distributed power generation. [0003] Due to the randomness and intermittent nature of wind energy ...
