The utilization of solar forecasting data for the proactive management of low voltage (LV) networks is in its infancy. However, it can now be shown to play an important role in the ‘smart grid’ context . This webinar will present three cases studies from Australian low voltage network operators (DNSPs - distribution network service providers) who have been given access to high resolution solar forecasting data for the purposes of evaluating the use of the technology for LV network management.
The first of the selected use cases focus on how solar forecasting data can aid decision making in day to day LV network operations. The second and third use case are closely related, and demonstrate how behind-the-meter solar forecasts allow LV network operators to generate more accurate gross load profiles, so that the underlying true demand can be estimated at the zone substation level, by combining these data with SCADA measurements. Additional examples will be included as time permits. The webinar will include background information, and additional descriptions of the solar forecasting methodologies, including how attendees can work with existing solutions to engage similar challenges for LV network management.

As more and more distribution assets are connected to the grid operations center, there is an opportunity to gain better insights and telemetric information that serves to inform and enable greater levels of control. In a similar manner, the explosion of the Internet of Things is bringing new dimensions to the ability to link localized sensor and control schemes. The convergence of these two areas now enable a new dimension of expanded and more granular control. This webinar will cover the sensors that enable this, the communications networks that unlock this potential and the enterprise and operational systems need to orchestrate this.

More extreme and frequent weather events, aging infrastructure, and poor vegetation applications have caused a sharp increase in utility power outages over the last few decades. This webinar talks about advanced analytics and how machine learning techniques can create a number of powerful outage management solutions including vegetation management, outage prediction, and resource optimization. When effectively developed and deployed, these solutions can significantly improve grid reliability, storm response efforts, and customer satisfaction for utilities.

Cyber security has become a critical priority for electric utilities across the power delivery, fossil generation, and nuclear power sectors. The evolving electric grid is increasingly dependent on information technology and telecommunications infrastructures to ensure its reliable operation. As generation plants are being required to adapt to the complex demands of an ever increasingly competitive marketplace, each power generation site is deploying more digital Instrumentation and Control assets from a variety of vendors. This presentation provides an overview of key cyber security objectives for the industry, research gaps, and suggested next steps to meet these challenges and improve the security and resiliency of the electric sector.

This presentation will describe the origins of Grid Modernization and propose a readiness determination methodology. This methodology will then show how to develop a grid modernization project in a rigorous fashion to meet clearly defined goals. Following this, a framework for one aspect of Grid Modernization, resiliency, will be presented along with a case study to highlight the application of resiliency concepts to meet Grid Modernization goals..
This presentation will review the concept of interoperability and the IEEE Std 2030-2011, Guide for Smart Grid Interoperability of Energy Technology and Information Technology Operation with the Electric Power System (EPS), and End-Use Applications and Loads. It provides an overview the smart grid interoperability reference model (SGIRM).
A smart grid standardization roadmap was developed in 2010 by the IEC that is similar to the framework and roadmap developed by NIST. Standards developing organizations (e.g., IEEE) ─using an open and balanced consensus process─ are establishing standards for the smart grid, building off of the conceptual reference models produced by NIST.
IEEE Std 2030-2011 supports EISA, the NIST framework coordination efforts, IEC interests, and additional smart grid applications. It focuses on a systems-level approach to understanding and guidance for interoperability components of communications, power systems, and information technology platforms.
This landmark standard needs to be reinforced for Working Groups and users of standards.

Under the California Electric Program Investment Charge (EPIC -1) project for Distributed Control for Smart Grid, San Diego Gas & Electric conducted a demonstration of various DERMS use cases. The demonstration consisted of the modeling of two SDG&E substations and feeders with an open tie and various downline DERs and devices.
The software was written and delivered by Advanced Control Systems. The seminar will summarize the findings, benefits and recommendations related to a DERMS installation. The demonstration consisted of control of LTCs, Voltage regulators, capacitors, switches and DERs. The DERS were 2MW PV inverters with a 2MW energy storage unit, each operating with injection into the grid.
Various use cases were demonstrated to study quiescent and stress operating states including failure modes, low and high DER injection modes, low and high load conditions, with the transition performance between each mode of operation. Three classical control technologies were compared and will be reported for each demonstration.

The penetration of small-scale Distributed Generation (DG) such as photovoltaics (PVs) has increased dramatically in recent years and is expected to increase further in the future. Small numbers of DG cause few or no problems to the grid, but as the percentage of DG grows, power quality, protection, and safety concerns need to be evaluated. A number of software tools are available to perform a distribution system analysis with varying degrees of complexities – ranging from relatively simple screening analysis to sophisticated transient simulations. This presentation will review the type of planning tools that are available and inform which ones are suitable for the investigation of a particular DG impact. Furthermore, the presentation will discuss how Distribution System State Estimation in combination with sensor data collected on distribution circuits can be used in an operational environment to (1) improve distribution system models and (2) inform control decisions of Grid Management Systems.

Integrated Distribution Planning tools are integrating traditional capacity planning methods with distributed energy resource planning. These tools are becoming increasingly important as utilities plan, account for, and manage higher penetrations of grid scale renewables. This webinar intends to share insights including best practices, pitfalls, problems, and results of deploying an enterprise level roll-out.

The availability of flexible resources is becoming increasingly important with increasing renewable generation. As part of the ARPA-E NODES project, a group of researchers are working on aggregating distributed flexible loads and DERs to provide grid services while maintaining customer quality-of-service. The presentation will cover the development of flexibility forecasts that use weather forecasts and other data to estimate the reserve potential of aggregate loads and DERs. An optimization framework that enables aggregation of a large numbers of flexible loads and DERs and determines the optimal day-ahead schedule for these resources will be discussed. Finally, a scalable control architecture for coordinating and controlling the resources in real-time with low latency will be presented.
