| With the large-scale Internet application and the construction of digital economy,the demand for cloud computing is increasing day by day.At the same time,with the promotion of "double carbon" goal,data center micro-grid continues to develop,renewable energy has become the focus of choice for data center operators.Using renewable energy technology,data centers can not only effectively coordinate the load of the grid,but also significantly reduce their own energy consumption,thus saving a lot of power costs.Aiming at the problem of high energy consumption of data center and how to plan the renewable energy micro-grid,this paper mainly does the following work:Firstly,the microgrid architecture of data center and its related energy management are analyzed.The energy consumption status of data center is analyzed from three aspects:energy consumption structure,load characteristics and energy consumption model.This paper introduces the typical renewable energy power supply equipment in data center,and probes into the cooperative energy management of data center and power supply.Then,in order to save energy and make full use of the potential of renewable energy consumption in data centers,this thesis proposes a load management strategy based on heterogeneous servers to ensure the quality of service,maximize the use of renewable energy and save traditional energy as much as possible.Finally,aiming at how to plan the renewable energy micro-grid reasonably,a two-layer optimization model is established to minimize the operating cost and carbon emissions.The upper layer is data center micro-grid capacity planning model,and the lower layer is data center operation optimization model.Scene truncation method is used to solve the uncertainty of wind power and photovoltaic output and reduce the calculation complexity.This method can effectively reduce the annual conversion investment and operating costs and carbon emissions,improve operator satisfaction. |
