不确定和多变的可再生能源渗透率的增加带来了各种资源和电网运营方面的挑战。微观(家庭和小型商业)需求侧电网灵活性可能是整合风能和太阳能高渗透率的一种具有成本效益的战略，但探索必要的信息和通信技术(ICT)的文献和实地部署很少。提出了一种通过物联网(IoT)实现信息驱动网格灵活性的探索性框架，以及一个概念验证无线传感器网关(FlexBox)来收集必要的参数，以便充分监控和启动微观级别的需求侧。2015年夏天，在(尼加拉瓜)马那瓜市部署了30个传感器网关，为近期的小规模需求响应试点实施制定基线。FlexBox现场数据已经开始揭示环境温度和负荷能耗之间的关系、负荷和建筑围护结构能效挑战、延迟通信网络挑战，以及参与现有需求侧用户行为模式的机会。信息驱动的网格灵活性战略为开发新的技术、系统架构和实现方法提供了巨大的机会，这些新技术、系统架构和实现方法可以轻松地跨地区、收入和发展水平进行扩展。
The increased penetration of uncertain and variable renewable energy presents various resource and operational electric grid challenges 1 . Micro-level (household and small commercial) demand-side grid flexibility could be a cost-effective strategy to integrate high penetrations of wind and solar energy, but literature and field deployments exploring the necessary information and communication technologies (ICTs) are scant. This paper presents an exploratory framework for enabling information driven grid flexibility through the Internet of Things (IoT), and a proof-of-concept wireless sensor gateway (FlexBox) to collect the necessary parameters for adequately monitoring and actuating the micro-level demand-side. In the summer of 2015, thirty sensor gateways were deployed in the city of Managua (Nicaragua) to develop a baseline for a near future small-scale demand response pilot implementation. FlexBox field data has begun shedding light on relationships between ambient temperature and load energy consumption, load and building envelope energy efficiency challenges, latency communication network challenges, and opportunities to engage existing demand-side user behavioral patterns. Information driven grid flexibility strategies present great opportunity to develop new technologies, system architectures, and implementation approaches that can easily scale across regions, incomes, and levels of development.
