Abstract
Based on international standardization and power utility practices, this paper presents a preliminary and systematic study on the field of energy informatics and analyzes boundary expansion of information and energy systems, and the convergence of energy systems and ICT. A comprehensive introduction of the fundamentals and standardization of energy informatics is provided, and several key open issues are identified.
Keywords: Smart energy, ICT, Energy informatics
Introduction
With the changing of global climate and a world energy shortage, a smooth transition from conventional fossil fuel-based energy supplies to renewable energy sources is critical for the sustainable development of human society. Meanwhile, the energy domain is experiencing a paradigmatic change by integrating conventional energy systems with advanced information and communication technologies (ICT), which poses new challenges to the efficient operation and design of energy systems.
From a technical perspective, with the purpose of supplying end-users with energy service comes the design of energy systems.[1] From a structural point of view, all of the components in an energy system have connections with production, transition, delivery, and energy usage.[2] From the view of socioeconomics, an energy system includes energy markets and they treat it as a technical and economic system to satisfy consumers’ demand for energy in forms of heat, fuels, and electricity. Moreover, an energy system is subject to various influences, for instance, business models, markets, regulations, customer behavior and the natural environment. These definitions are related to information from a system (or system of systems) point-of-view.
In the process of smart grid development, most power companies have already deployed plenty of automation and information systems. In order to control and manage the power grid, some power companies have implemented intelligent energy dispatching systems, wide-area measurement systems, grid condition monitoring systems, electric vehicle charging monitoring networks, distribution automation systems, mobile operational applications for condition-based maintenance and advanced metering infrastructure, etc. At the same time, some power companies also have arranged enterprise ERP systems and centralized data centers in order to manage individual businesses effectively and efficiently.
The monitoring system of communication network and information system is isolated to a considerable extent and has failed to form a coordinated ICT (information and communication technology) monitoring system. It is very difficult to conduct a comprehensive analysis and evaluation based on the monitoring data of information and communication network operation. For example, it is unlikely to accurately locate where the fault or alarm occurs in an ICT system, meaning that it cannot adapt to future power grid operation and management needs. In the year 2011, SGCC (State Grid Corporation of China) built a unified ICT operation and monitoring center and put it into operation. This unified ICT operation and monitoring center enables the real-time monitoring of smart grid ICT, unified dispatch of ICT resources, and integrated security defense. The system ensures the security of company information and communication systems security operation.[3]
