The increasing availability of distributed generation (DG) in medium voltage feeders justifies the investigation of approaches that improve the utilization of these resources for the Volt/Var control. When DG production is mostly from renewable energy resources, the operation of these networks may represent a difficult task due the following causes: the point of connection of DG in an MV feeder may be at some distance from the buses of significant consumption and the production from nondispatchable DG is in general not synchronized with the demand. Without the implementation of an adequate control of DG outputs, these two causes may severely reduce the expected DG benefits, such as the reduction of peak loads, of power loss and congestions, the avoidance of network overcapacity, and the deferral of network reinforcements. This tutorial addresses the role of the increased use of information and communication technologies (ICT) in the integration of DERs, and to this aim we describe the example of a multiagent system (MAS) approach for the Volt-VAR control (VVC) tested using an ICT-power cosimulation platform specifically developed for the purpose.

Electricity (or Electric Energy) is the heart and soul of our modern civilization and is one of the
most essential commodities on this planet for the progress of humanity. Roughly 40% of the
total primary energy used in world is in the form of electricity. As the world’s economy
progresses and income rises, growing population demand more energy. Today there are over 7.6
billion people in the world. It is expected to reach around 10.0 billion by the year 2050. By
many estimates, roughly 1.1 billion (around 15%) of the world population in 2017 do not have
any access to electricity. More population means more demand for energy and electricity.
This presentation takes a holistic look at the energy sustainability for the planet earth with special emphasis on the production and usage of electricity It is designed to open-up a meaningful conversation between the various stakeholders about energy sustainability Special attention will be given to Wind Farms and Large Scale PV power: Challenges and Opportunities.

Modern society has reached a point where virtually every crucial economic and social function depends on the secure, reliable operation of the power and energy infrastructures. The energy industry worldwide is experiencing significant changes caused by rapid technology transformation, security, environmental concerns and climate changes, evolving consumer needs and associated interrelations. The initiatives we undertake today affect the way in which the grid is operated and maintained in the future. Sustainability roadmaps and efforts, to improve the performance of electric utility systems and address the energy needs of society, offer many lessons learned and winning strategies.
This Tutorial will explore business models and supply chain realities in the scope of power system technology transformation, lessons learned from deployment of advanced technologies, strategies and operational aspects of managing grid system and equipment assets to build a more resilient and efficient grid to strengthen our systems organically and digitally. At the transmission level, wide-area measurement is increasingly becoming the next generation SCADA. There is a growing need for use of technologies to minimize potential for cascading outages, and the emergence of production type tools that can better manage grid stability, especially in light of the increased penetration of renewables worldwide.
Core content focuses on Key Success Factors for Modernizing the Electrical Grid to provide reliable, secure, safe, and cost-effective delivery of electrical energy. In-depth featured topics dive into energy trends and industry sustainability, grid resiliency and modernization efforts and the required performance levels. Use of Advanced Test Facilities will showcase endeavors and findings and highlights the importance of industry Standards. Practical experiences with cyber security and vulnerability assessment testing, available solutions, findings in test and production environments, and roadmaps for coordinated plans across multiple lines of business, Regulatory Standards for addressing Digital Threat will be reviewed. Experiences and methods for testing, and benefits for stronger partnering with manufactures, in support of life cycle deployment, will be covered.

The modular multilevel converter (MMC) is an advanced converter topology that is changing the
scenario of high-voltage direct current (HVDC) transmission systems. The MMC was first proposed
in 2003 by Marquardt, and since then it has been an important focus of research for industry and
universities. A three-phase MMC is integrated by six arms (two per phase-leg), each of them
involving many cascaded submodules. The MMC offers an expandable and redundant configuration
capable of generating a large number of voltage levels operating with high efficiency and reduced
switching losses. This tutorial will introduce the operation principles of the MMC and some recent
research advances, including modulation techniques, capacitor voltage balancing and control
techniques for the circulating currents.

PV solar systems are being deployed across the world at a very rapid rate. However, high
penetration of PV solar systems presents several challenges such as reverse power flow, voltage
rise, temporary overvoltages, frequency variations, etc. Smart inverter is an emerging technology
which helps obviate several of the above challenges. While conventional solar inverters generate
only real power, smart PV inverters provide both reactive and real power modulation in addition
to real power generation. This Tutorial will describe the grid integration challenges of PV solar
systems. It will further present the concepts of smart inverters and different smart inverter
functions such as volt-var, volt-watt, Low/High Voltage Ride Through, Low/High Frequency
Ride Through, Dynamic Reactive Current Injection, ramp rate, etc. The different grid support
benefits provided by smart inverters will be presented. Novel smart inverter technologies will be
described together with issues of control coordination of smart inverters.

Distribution Automation became a reality in the early 1980s with the evolution of
distribution control centers. The concept of microgrids and their automation followed suit
and became a reality in the last decade. These dramatic changes occurred due to the
integration of renewable energy sources, energy storage, and other related
technologies. Source and load control at the distribution level are key requirements of
the evolving system. These activities require distribution automation strategies that take
advantage of available technologies, while promoting newer technologies. It is
necessary to create a roadmap for holistic distribution automation strategies in a
smarter grid. Sustainable and resilient grid development is a paradigm shift requiring a
new line of thinking in the engineering, operation and maintenance of the power system.
Distributed control architectures based on dynamic load and source data should be
explored as a possible solution.
In this tutorial presentation, the first part will examine the tremendous progress made in smart grid automation due to innovative technologies, power and power electronic devices, sensors, faster communication systems, and computational paradigms. The presentation will then gravitate to the recent advances in microgrid automation. The emphasis is on all aspects: sensing, control, protection, switching to assure higher reliability, resilience, safety and reduced cost. Several on-going projects and their progress will also be explored. The goal of this presentation is to open the dialog with the audience for active interaction of Innovative ideas.

This tutorial will focus on the operation and control of power systems in presence of renewable
energy sources (RES). With the enhanced controllability of RES being used in microgrid and
distribution networks, several tasks can be accomplished over and over the conventional constant
active and reactive power (P-Q) dispatch. While the RES are mostly inertia-less sources,
modifications in the control loop can be made for obtaining virtual inertia. Besides, services such as
voltage and frequency regulation, short term frequency and voltage response, and power quality
improvements at a distribution level can also be evoked from the solar PV based inverter. On the
other hand, RES are intermittent and uncertain in nature and can be addressed by V2G technology that
is emerging in power markets. The tutorial will also discuss the issue i.e., voltage rise problem that
arises due to photo voltaic located towards the end of a residential feeder.
