Embodiment Construction

[0073] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0074] Such as figure 1 , providing a multi-spatial-scale gradual optimization method for designing a power load dispatching mode, the method comprising the following steps:

[0075] Step 1: Extract the response characteristics of dispatchable loads with multiple time scales;

[0076] Step 2: Design a hierarchical load scheduling model based on load proxy;

[0077] Step 3: Design a power load dispatching model that gradually becomes better at multiple spatio-temporal scales.

[0078] In the step 1, the power consumption information of the dispatchable load is collected, and the collected power consumption information is analyzed and evaluated to obtain the multi-time scale response characteristics of the dispatchable load.

[0079] The electricity consumption information includes residential electricity consumption information (electricity consumption info...

Abstract

The invention provides a multiple spatial and temporal scale gradually-advancing load dispatching mode designing method. The method comprises the following steps: extracting the responding characteristics of schedulable load multiple temporal scales; designing a layering load dispatching mode based on load acting; designing the multiple spatial and temporal scale gradually-advancing power load dispatching mode. The multiple spatial and temporal scale gradually-advancing load dispatching mode designing method configures load side sources in day-ahead, intra-day and real time and other temporal scales and promotes the load side sources to participate in the dispatch and the operation of a power grid together with a generating side unit, so as to be favorable to improving the utilization rate of power equipment, promotes a daily load curve to gradually tend to be smooth, reduces the valley-to-peak difference of a system, and has great potentiality in promoting the digesting and saving aspect of large-scale renewable energy sources.

Description

technical field [0001] The invention belongs to the field of dispatching operation control of a smart grid electric power system, and in particular relates to a design method of a load dispatching mode that is progressively optimized at multiple temporal and spatial scales. Background technique [0002] Judging from the electricity load statistics of various countries, more than 95% of the peak load lasts only a few dozen hours a year. It is not economical to increase the installed capacity of peak-shaving power generation to meet this part of the peak load. In addition, due to the "unfriendly" characteristics of intermittent energy such as volatility, anti-peak regulation, and low dispatchability, the rapid growth of its installed capacity has increased the difficulty of power grid dispatching and operation, especially for power system adjustment capabilities. major challenge. [0003] As one of the instantaneous power balance of the power system, the conventional adjustab...
