Idc energy storage concept

How much energy do IDCs use?

According to the United States Data Center Energy Usage Report (Ref. ), IDCs in the U.S. consumed an estimated 70 billion kWh in 2014, accounting for about 1.8% of total U.S. electricity consumption. Ref. shows that the energy demand from IDCs in 2019 was around 200 TWh, comprising around 1% of global electricity use.

What is a networked internet data center (IDC)?

The computer resources are hosted in and the user’s requests are handled by multiple networked Internet Data Centers (IDCs) that would be located in different geographical locations. 1.1. Related work As the backbone of cloud computing, IDCs are large energy consumers.

What is the computing capacity of an IDC?

The computing capacity of an IDC is defined as the maximum number of requests it can handle in one time slot. For an IDC with m server racks, its computing capacity is mμ. Meanwhile, the maximum number of requests it can buffer is mQ.

How do we determine the capacity of cyber-physical resources in IDCs?

The model determines the capacity of cyber-physical resources in IDCs (servers, on-site BESSs, and renewable energy sources) through solving an optimization model that minimizes the IDC network’s investment, operation, and reliability costs. Ref. proposes a hierarchical planning framework for an IDC network.

Should power utilities invest their own IDCs?

With deep integration of cloud computing in industrial systems, there is an emerging trend that power utilities invest their own IDCs (i.e. private IDCs that only provide access to grid stakeholders and other authorized parties) to provide cyber infrastructure support for grid operation.

What is a power grid integrated with networked IDCs?

The schematic of a power grid integrated with networked IDCs is depicted in Fig. 1. The IDCs communicate with each other through a communication network. The communication network consists of a number of information nodes that are interconnected by communication links.
