日益复杂的电网、不断增长的需求、更高可靠性、安全性和效率的要求，以及对环境和能源可持续性的关注，继续凸显了在利用通信和信息技术方面实现巨大飞跃的必要性。这种向“更智能”电网的飞跃被广泛地称为“智能电网”。这些技术内聚集成的框架有助于迫切需要的标准的融合，并实现必要的分析能力。本文批判性地回顾了可再生能源、需求响应和存储等主要智能电网资源对可靠性的影响。我们观察到，这些资源的理想组合会导致更平坦的净需求，最终进一步加剧可靠性挑战。在促进现代网络安全措施的同时，提出了网格范围的IT体系结构框架来应对这些挑战。该体系结构支持多种地理上和时间上协调的分层监视和控制操作，时间尺度从毫秒到更高。
Increasing complexity of power grids, growing demand, and requirement for greater reliability, security and efficiency as well as environmental and energy sustainability concerns continue to highlight the need for a quantum leap in harnessing communication and information technologies. This leap toward a ¿smarter¿ grid is widely referred to as ¿smart grid.¿ A framework for cohesive integration of these technologies facilitates convergence of acutely needed standards, and implementation of necessary analytical capabilities. This paper critically reviews the reliability impacts of major smart grid resources such as renewables, demand response, and storage. We observe that an ideal mix of these resources leads to a flatter net demand that eventually accentuates reliability challenges further. A gridwide IT architectural framework is presented to meet these challenges while facilitating modern cybersecurity measures. This architecture supports a multitude of geographically and temporally coordinated hierarchical monitoring and control actions over time scales from milliseconds and up.
