An optimal design method for backup energy system of green data center

Abstract

The invention discloses a green data center standby power system optimization design method, which comprises the steps of: establishing a data center load model, a generalized energy storage system model and a mobile power-generating vehicle model; determining user UPS and mobile power-generating vehicle information of an electric power company; determining magnitude of compulsory protecting load within different time periods after power outage; determining an energy supply strategy of an emergency energy system; and determining capacity and components of the emergency energy system based on the data center load model, the generalized energy storage system model and the mobile power-generating vehicle model, and finally establishing a standby power system capacity optimization model based on a generalized energy storage system and the mobile power-generating vehicle. The data center standby power system capacity optimization design method is based on cooperation of the generalized energy storage system and the mobile power-generating vehicle, can greatly reduce expensive electric energy storage system capacity in a self-provided energy system through configuring a cold energy storage system on the premise of satisfying highly reliable energy supply and green and environment protection requirements of the data center, saves investment and operation cost, and reduces whole life cycle cost.

Description

technical field [0001] The invention belongs to the technical field of user backup energy capacity planning, design and optimization, and in particular relates to an optimization design method for a green data center backup energy system. Background technique [0002] With the continuous advancement of networking and informatization in various industries, and the rapid development of Internet +, the number of data centers in my country has grown rapidly. According to statistics, the number of existing data centers in my country accounts for about 13% of the global total. The energy consumption demand of the data center has the characteristics of high power density, large cooling load demand, and high reliability requirements. The data center unit is required to run uninterrupted throughout the year, and is generally supplied by more than 2 mains electricity sources, and a diesel generator with sufficient capacity is also required as a backup. With the improvement of the re...
