The Smart Grid describes a next-generation electrical power system that is typified by the increased use of communications and information technology in the generation, delivery, and consumption of electrical energy worldwide.
IEEE Smart Grid hosts a series of complimentary webinars on varying aspects of global grid modernization.
Predictive Analytics for Power Systems Decision Making
Presented by: Rui Yang
Thursday, April 25th, 2019 1:00PM EDT
Increasing amounts of heterogeneous sensor data and information are becoming available in energy grids from sources such as smart meters, distributed generation, and smart home energy management systems. Being able to collect, curate, and create actionable information with these data will be crucial to power systems operations with the increasing penetrations of distributed energy resources. In this webinar, we will present NREL’s latest work on developing predictive analytics to facilitate the real-time decision making in power systems operations. In this work, a high-precision predictive state estimator is first developed which employs sparse measurement data to provide system-wide awareness in distribution systems, while traditional state estimation techniques have difficulty coping with the low- observability conditions often present on the distribution systems due to the paucity of sensor measurements. Based on the predicted system conditions, grid operators can proactively control all the flexible resources by employing coordinated optimization techniques. The developed technologies allow grid operators to manage power systems with lean reserve margins while maintaining and enhancing grid reliability with high penetrations of renewable energy resources.

Coordinating of Energy Storage and Flexible Demand Resources
Presented by: Prabir Barooah
Thursday, May 2, 2019 1:00PM EDT
Energy storage is needed to help the power grid of the future in balancing the highs and lows caused by intermittent renewables such as solar and wind. Flexible demand – such as air conditioning – can provide the same service as batteries by manipulating their demand around a nominal baseline so that the increase and decrease of demand appears like charging and discharging of a battery. The advantage of these “virtual batteries” over real batteries is their low cost, since only a change in software is needed. A challenge in the effective use of both real and virtual batteries is coordination: a large number of them need to be coordinated so that together they supply what the grid needs. At the same time, the Quality of Service (QoS) of each consumer – on whose premises a flexible load or a battery resides - must be maintained within strict, pre-negotiated, bounds. In this webinar, we will describe methods for coordinating a large number of energy storage and flexible demand resources, and discuss the pros and cons of these methods. ile maintaining and enhancing grid reliability with high penetrations of renewable energy resources.
