Power system dispatching method based on interactive operation of data network and power network

Abstract

The invention discloses an electric power system scheduling method based on data network and electric power network interaction operations, and belongs to the electric power system economical scheduling technical field; the method comprises the following steps: considering the influences of active server quantity on the data center power consumption, and building an electric power system scheduling model containing data network power consumption constraints; using the electric power system scheduling model to distribute active outputs for all units and data centers; considering active server quantity related delay influences, and building a data center network load distribution model; carrying out optimal allocations for each data center network load according to the active output of each data center, thus fusing the data center loads with an existing scheduling model without affecting the data center service quality, and realizing friendly interactions between the data network and the electric power network.

Description

technical field [0001] The invention discloses a power system scheduling method based on the interactive operation of a data network and a power network, and belongs to the technical field of power system economic scheduling. Background technique [0002] With the development and improvement of smart grid and power market, rational excavation and dispatch of demand-side resources has become an important way to improve the comprehensive operation efficiency of the power system and optimize resource allocation. In recent years, with the rapid development of Internet technology, the scale and number of global data centers are rapidly expanding. Data centers have become a considerable amount of power load, and the scale of global data centers is still expanding rapidly. The addition of this load will increase the volatility of the power load in the area, making it difficult to ensure the stable power supply of the data center, and also increase the risk of safe and reliable oper...

Problems solved by technology

[0003] At present, most of the energy management research of distributed data centers at home and abroad are focused on minimizing the energy cost of data centers, without considering the impact of this energy management practice on the power grid

A recent foreign article mentioned that the power company guides the active redistribution of data center load by choosing an appropriate real-time pricing mechanism, so as to achieve the purpose of power load balance and achieve a win-win situation of data center cost reduction and grid stability. It is very difficult to control the data center load under the current status of China's smart grid infrastructure and power market construction. Therefore, it is of great significance to study the load characteristics of the data center and the direct dispatch of the data network to the power grid.
