Foundational Support Systems Webinars
Presented by: Ioannis Antonopoulos, Benoit Couraud, and Valentin Robu
In the recent years, there has been a growing interest for the use of Distributed Demand-Side-Response (DDSR) to regulate the power system. DDSR consists in the coordination of distributed loads such as industrial, commercial and recently residential end-users to contribute to electricity suppliers’ portfolio balance or frequency regulation. The integration of commercial and residential end-users into DDSR comes with the need for Big Data Analysis and Artificial Intelligence (AI) solutions to optimize the contribution of these distributed assets. In this webinar, we describe what the key challenges of DDSR are, and how AI and Machine Learning (ML) solutions can address these challenges. Based on a recent review of research works and industrial projects, we will detail the principles of the most relevant AI techniques and will explain how they are used in the context of DDSR. Finally, we discuss a number of directions for future research in this area.

The high proliferation of inverter-interfaced Distributed Renewable Energy Sources (DRES) at distribution grid level will gradually replace the conventional fuel-driven synchronous generators (SGs) at transmission system level. The inverter-interfaced DRES are mostly driven by variable-output RES such as PV or wind plants and for this reason are considered as non-dispatchable. There are DRES employing SGs directly connected to the grid which are mostly driven by biomass or small-hydro units, thereby considered as dispatchable. Although non-dispatchable, the inverter-interfaced DRES are highly controllable, thus able to provide a number of new services. DRES, particularly the inverter-interfaced ones, must urgently adopt a new more active role in the electricity networks by providing Ancillary Services (AS) similarly to the conventional SGs and even new ones within the distribution grids in order to keep the system stability and robustness. Such AS include: inertial response, active power ramp rate control, operation in frequency sensitive mode, voltage regulation, contribution to fault clearing and harmonic mitigation. This webinar will provide suggestions on (i) how to control the DRES inverters, so that they behave as controllable SGs able to provide the aforementioned AS in a unified way; (ii) methods to aggregate frequency related AS to be offered to the transmission system; (iii) methods on the measurement and quantification of various AS, so that they are transformed from system support functions into tradable AS; (iv) methods for testing the DRES inverters with respect to the new AS. The webinar will also present the obstacles posed by current grid codes, standards or market regulations for the introduction of the new AS and provide suggestions on lifting those obstacles. It is noted that batteries, although not a conventional type of RES, are included in this webinar, since they can provide a number of the aforementioned AS either by themselves or in combination with the non-dispatchable DRES.

IEEE SA is at the forefront of developing standards for the smart grid, starting with the smart grid vision documents in collaboration with the IEEE Smart Grid Initiative that was developed more than 10 years ago focusing on five key aspects of Smart Grid implementation. IEEE-SA has more than 100+ key standards in the area of smart grid and also participated in the development of the "US NIST Framework of Standards and Protocols for the Smart Grid".
The talk will focus standards from IEEE focus that range across the spectrum from Substation Automation, Renewable Energy, Energy Efficiency, IoT/Communication Protocols, and Advanced Metering Infrastructure to name a few and encompasses the end-to-end implementation that includes power and energy generation and transmission, communications and information technology. IEEE SA is also focused on standards implementation through the IEEE Conformity Assessment Program (ICAP) and that talk will cover some of the key certification programs focused around Smart Grid.

If we assume that The Green New Deal and Transactive Energy are will happen, we need to realize that no one is ready for what will happen in the next decade.
In a project to determine how many devices will play in the future grid, the numbers were staggering. This presentation will go thru what will be contributing to big data going forward and what that means from an aggregate number of data points, and requirements for processing, and the required system latency if we move to electrification, transactive energy, and 100% renewables. Simply staggering gaps exist between what happens today and what needs to happen.

Modern life has grown to be extremely dependent on electric power. As the world’s services increasingly electrify, the resilience of the electric power grid is more important than ever. Current methods of studying electric power grid resilience generally fall in one of two categories: (1) N-1 type contingency analysis, and (2) network science methods based upon graph connectedness. The latter use “lightweight” graph models while the former is particularly computationally intensive. Though these methods provide valuable complementary insights, there is a new need for analytical tools that balance analytical insight with computational complexity.
This webinar discusses a set of new resilience measures based upon the application of hetero-functional graph theory to electric power systems. These measures are of particular relevant to the grid’s architectural transformation as it comes to accommodate distributed generation at the grid periphery. Furthermore, the webinar will discuss some of the key differences between existing resilience measures and the newly introduced measures.

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.

With the increasing penetration of intermittent renewable energy, responsive loads, and microgrids, the power system has been subject to different types of dynamics. Consequently, the static state estimation (SSE) used in today’s energy management systems may be unable to capture these dynamics in an operational environment. As a result, new monitoring tools need to be developed, such as dynamic state estimation (DSE). The capability of DSE to accurately capture rapid dynamic changes in system states plays an important role in power system control and protection. Thanks to the widespread deployment of phasor measurement units, the development of a fast and robust DSE becomes possible. This webinar will present a comprehensive view of the DSE, in terms of its motivations, concepts, implementation and utilization. The similarities and differences between DSE and other existing estimation methods will be clarified as well.

Part 2 : The Smart Grid Emerges
Carl Sagan said, “You have to know the past to understand the present”. Most everyone knows something about the emerging smart grid. However, not everyone knows the whole story about how and why the smart grid began. It is not only fascinating, but also useful to understand the underlying causes that led to the emergence and continuing development of a smart grid. It’s all about changing technologies and business models. In Part 2 of this webinar we will discuss how disruptive new technologies have emerged to produce, store, and manage energy, both on the supply side and the demand side, resulting in much more complexity in the operations of the electric grid. We will examine how information and communications technologies are enabling a smart grid which will ultimately become a cyber physical system.

Part 1 : Eroding the Foundations of the Legacy Electric Grid
Carl Sagan said, “You have to know the past to understand the present”. Most everyone knows something about the emerging smart grid. However, not everyone knows the whole story about how and why the smart grid began. It is not only fascinating, but also useful to understand the underlying causes that led to the emergence and continuing development of a smart grid. It’s all about changing technologies and business models. In Part 1 of this webinar we will examine why and how the foundations of the century old legacy electric grid have eroded, beginning in the 1970s in the aftermath of the OPEC oil embargo. Longstanding favorable economics, acceptable reliability, stable monopoly business model, and standard utility operations were adversely affected.
