Construction method of active power distribution network planning model considering data center

Abstract

The invention discloses an active power distribution network planning model construction method considering a data center. The method comprises the following steps: acquiring basic parameters; establishing an active power distribution network planning model considering the data center by using a two-stage stochastic optimization method; substituting the basic parameters into the model, and solving the model by adopting an improved group search optimization algorithm with the goal of minimizing the investment operation cost of the active power distribution network and improving the utilization rate of renewable energy sources and reducing the carbon emission, and outputting schemes of the selected model of the transformation line, the installation position of the intelligent electric meter, the installation position of the wind turbine generator, the number of started servers in each time period of the data center, the time dimension task migration quantity in the data center, the electricity purchase quantity of the distribution network, the actual output of the wind turbine generator, the energy storage charging power and the energy storage discharging power. According to the method, the time dimension transferable load of the data center and the flexible charging and discharging performance of the equipped energy storage equipment are considered, the planning cost of the active power distribution network can be effectively reduced, distributed energy consumption is promoted, and carbon emission is reduced.

Description

technical field [0001] The invention relates to the field of electric power systems, in particular to a method, device and computing device for constructing an active distribution network planning model considering data centers. Background technique [0002] In recent years, the Industrial Internet and the digital revolution have driven the construction of a new generation of power systems, and demand for big data and cloud computing has exploded. In the past five years, the growth rate of data center (DC) construction in China has been maintained at around 20%, the annual electricity consumption accounts for more than 2% of the country's power generation, and it contributes about 0.3% of global carbon emissions. With the development of communication technology, the number of data processing tasks performed by data centers continues to increase, resulting in a rapid upward trend in the power consumption of data centers.
