Description

Space-time resource scheduling system based on big data
Technical Field
The invention relates to the technical field of power control, in particular to a space-time resource scheduling system based on big data.
Background
From the statistical data of the electric load of each country, the accumulated duration of peak load year of more than 95% is only tens of hours, and the method of increasing peak shaving power generator is not economical to meet the peak load. In addition, due to the 'unfriendly' characteristics of the intermittent energy source, such as volatility, anti-peak regulation performance, low schedulability and the like, the rapid increase of the installed capacity increases the difficulty of power grid scheduling operation, and particularly provides a new significant challenge for the power system adjusting capability. In addition, in the prior art, the research on a dispatching strategy optimization method under the influence of a multi-dimensional dynamic space-time factor, the research on a multi-digital safe misoperation prevention method of full scene dispatching and the research on a method for improving and converting the electric dispatching of the distribution network into a full-scene Jing Zhihui dispatching system are also lacking, and more convenient technical service and support are provided for related professions of the distribution network.
For example, the prior art of CN103296682B discloses a load scheduling mode design method with gradually optimizing multiple time-space scales, which is used as a party for power instantaneous balance of a power system, and the conventional adjustable load plays a certain role in maintaining economic, safe and reliable operation of the power system. In recent years, electric vehicles with bidirectional interaction capability with a power grid, energy storage and specific gravity of energy storage in loads are in a continuous trend. The perfection of the load side communication and information interaction support facilities makes the schedulable load an important means for keeping the balance of power supply and demand.
Another exemplary robust energy scheduling method based on two-stage energy and traffic space-time matching, as disclosed in the prior art of CN111047227B, is that in the time dimension, the existing energy management and control strategy deals with the time-varying characteristics of renewable energy and mobile traffic by mainly adjusting the variables such as the transmit power of the base station, the charging and discharging rate of the base station battery, the pre-purchase of electric quantity, and the real-time purchase, so as to reduce the consumption of grid energy. In the space dimension, the existing energy management and control strategy mainly achieves space matching of energy and service through energy sharing or load balancing among base stations. For example, to fully exploit the diversity of renewable energy sources in the spatial dimension, the consumption of grid energy is reduced; however, in the prior art research on the energy scheduling method based on robust optimization, energy scheduling is only carried out from a certain dimension of time or space, the two dimensions are comprehensively considered by fresh articles, and unilateral energy scheduling from the time or space dimension cannot truly realize energy-service space-time matching, so that the renewable energy utilization rate is lower.
The invention is designed for solving the problems of poor resource scheduling, low utilization rate, low supply and demand balance means, low space-time resource utilization dimension and the like in the prior art.
