by Editor on January 4, 2017

A new edition of the Newton-Evans Market Trends Digest is now available:

This issue includes:

  • A look back at the Worldwide Protective Relay Marketplace study completed last month
  • Progress report and interim findings from the 2017-2019 SCADA, EMS, DMS and OMS global market study
  • Excerpts from a 2016 study on the need for third party consulting services in the areas of metering, OT and NERC CIP compliance
  • Observations on the Metering, AMI and related Telecommunications Market

We look forward to sharing more energy industry market intelligence in 2017.

The Newton-Evans Research Company has released preliminary findings from its current study of EMS, SCADA, DMS and OMS usage patterns in North American electric power utilities, one of four component reports of the company’s global market assessment series on operational control systems.

Among the initial observations gleaned from interviews and surveys with over 60 officials from a broad range of U.S. electric utilities:

  • Plans call for upgrades or retrofits to SCADA and OMS systems among a large percentage of these utilities
  • 20% of utilities sampled plan to purchase a new or replacement DMS. 30% indicated that they have or plan on having an Advanced DMS by year-end 2019.
  • Nearly one-half of the respondents reported having real-time linkages in place between SCADA and outage management systems.
  • Third party services are being used and relied upon to assist with NERC CIP compliance issues and for the conduct of vulnerability assessments.
  • DNP 3 continues to be the most prevalent operational data communications protocol throughout North American electric power utilities. Plans call for continuing the use of DNP 3 for the foreseeable future among most of these utilities.
  • The major use of analytics tools is in outage management activities such as fault location determination.
  • More topics surveyed in this new study include: the impact of NERC CIP compliance on budgets and workloads; cyber security issues; telecommunications strategies and methodologies; distribution network model maintenance; changing organizational responsibilities for control systems; budget outlooks; and, DMS applications usage patterns.

    There have been some changes over the last few years in utility organizations with respect to control system support staff. IT departments are now the principal support group in nearly one-third of utilities sampled so far, while 47% report the “OT” organization continuing as the primary support unit. Eighteen percent indicated that both IT and OT staff share responsibility for supporting control systems. See Figure 1.

    The types of networks used for data communications from the substation to the control system vary widely, with most utilities reporting use of multiple networks for the mix of data acquisition requirements. See Figure 2.

    The North American market report is one of four volumes being produced for the company’s fifteenth series of EMS, SCADA and DMS studies published by Newton-Evans Research since 1984. Work on the other three volumes is underway; the entire series will be published during the first quarter of 2017.

Global Study Finds Continuing Moderate Growth in Protective Relay Market with Commitment to Improving Protection Coordination and Grid Security Practices

Role of Synchrophasors and Teleprotection Continues to Expand; Provides Better Situational Awareness and Visualization for Control System Operators

Newton-Evans Research Company has completed a six-month research study and survey of protective relay usage patterns in the world community of electric power utilities. Findings from 114 large and md-size utilities in 28 countries point to some newer trends in adoption and use of protection and control technology.

Among the key findings reported in the four-volume study are these:

  • Most new and retrofit relay units being purchased are digital relays, but in some of the protection applications studied, such as motor protection and large generator applications, and in installations where electrical interference is strong, electromechanical and older solid state relays continue to have a niche market position.
  • The annual world market for protective relays and related power systems protection devices continues to grow at a moderate pace that exceeds many other categories of electric utility investments for grid modernization.
  • Manufacturers of protective relays continue to expand their market coverage, with more than 20 firms each enjoying at least some share of the global market.
  • Real-time analysis of synchrophasor data is becoming a major application for the emerging field of operational analytics.
  • Communications protocol usage patterns continue to serve as a key differentiator between large and mid-size North American electric utilities and their international counterparts, as shown in the accompanying chart.

The 2016 Newton-Evans survey of electric utilities includes more than 20 detailed product functionality topics, related technical questions, and market-related issues, together incorporating more than 250 data points of information from each of the participating utilities.

Guest Article by Vince Martinelli

The reliable operation of the North American power grid is testament to the quality of design, planning and execution over multiple generations of utility engineers. As part of this progression, previous grid modernization efforts added high-performance sensing and communications technologies, first to generation and transmission, and eventually to the distribution system. These technologies helped utilities squeeze more capacity and resiliency out of existing assets cost-effectively, reacting to changes driven by load growth and diversification, as well as industry restructuring.

These trends led to broadly deployed “automation” in the medium-voltage (MV) portion of the distribution system. Medium-voltage substations, where high-voltage power is stepped down to MV on its path toward end customers, have seen the greatest degree of automation. Combined with automation at some of the MV devices downstream from the substation, such as reclosers, capacitor banks and line regulators, this provides the ability to measure and control the system with higher fidelity as compared to managing from the transmission layer. Utilities have evaluated technologies, tested specific solutions in trials, validated use cases and financial models, and made prudent investment choices in rolling out MV automation.

History Repeating Itself
A similar “automation” transition is now happening at the low-voltage (LV) level. Driven by higher reliability expectations, growth of rooftop solar PV generation, energy efficiency programs, the emergence of electric vehicles in the transportation mix, and the promise of battery storage for a range of grid-connected applications, new pressure is being placed towards the edge of the grid. It is more acute in some service areas than others, and can be clustered within one utility’s territory – or even within specific feeder circuits. Driven by these trends, the next frontier in grid modernization is at the interface between the MV distribution layer and the LV distribution layer, centered on the humble distribution transformer, as represented in Figure 1.

Figure 1. LV Substations provide critical new capabilities for grid modernization.

Similar to the MV automation rollout, LV substation modernization will happen first at acute “pain points,” becoming more widespread as the technology matures and the detailed use cases are developed.

Active LV Substations Solve Multiple Problems
Among the variety of potential applications, local voltage regulation is a clear “pain point” that cannot be addressed at the MV layer alone. Whether for increasing PV hosting capacity at the neighborhood level by countering voltage rise during reverse power flow, or for supporting energy efficiency programs where the goal is to deliver voltage to customers at the lower end of the acceptable ANSI A range, the benefits of adding automation to the distribution transformer – what we refer to as an LV substation – are becoming clear.

Figure 2 shows two examples of LV Substations deployed by U.S. electric utilities. In each case, a standard distribution transformer is paired with a grid automation device providing control with power electronics-based multi-function regulating capabilities, visibility with onboard current and voltage sensors, and automation with processing and memory components and communications capabilities. These regulating functions include voltage regulation in forward and reverse power flow, power factor correction, and harmonics mitigation. The system also reduces voltage sags, swells, and flicker for the customer connected downstream.

These compact, maintenance-free systems take advantage of existing “real estate” on poles and pads, simplifying the easement process and providing an alternative to costly upgrades on the MV system. The flexible communications platform can integrate with SCADA on the MV system and interact with downstream LV devices, such as AMI (“smart meters”) or behind-the-meter resources, such as next-generation smart inverters, EV chargers or energy storage resources.

Figure 2. LV Substation implementations for (a) an overhead system and (b) underground plant, featuring coupled integration with a distribution transformer for siting on a standard pad in a residential area. Adding a power electronics-based regulator with integrated sensing, computing, communications and control software brings grid modernization to legacy distribution transformers.

Figure 3 shows voltage data at a particular customer meter over several months without grid automation; then with the voltage regulation from the LV Substation in place. Voltage variability before upgrading the system reflects MV voltage variations, with dips well below ANSI limits, as delivered to the distribution transformer. When the power electronics regulator is activated with an initial setpoint at 240 V, the only variability at the customer is the load-dependent voltage drop on the LV line itself. This particular customer, and neighboring customers behind this LV substation, now receive compliant voltage and superior power quality, independent of the bulk MV system.

Figure 3. Customer voltage delivery improvement measured by utility AMI voltage data showing the control provided by power electronics voltage regulation after introducing the automated LV Substation.

Looking Toward the Near Future
The daily news cycle reminds us that the forces putting pressure on the distribution grid are accelerating, driven largely by changes in how customers choose to participate in their energy future. Whether it’s Hawaii mandating a 100% renewables goal; solar power’s levelized cost of energy continuing to plummet; New York’s REV plan; the ongoing retirement of coal-fired power plants; or nationwide deployment of EV charging stations, the trends are clear.

Fortunately, the concept of automated LV Substations – elevating the status of the long-serving distribution transformer – provides a capital-efficient blueprint for a path forward, modeled after the successful rollout of automation in the MV distribution layer. The difference today is that localized pressure points call for localized solutions appropriate for the demands of the LV layer. The evolution of power electronics-based system designs has resulted in compact, reliable and cost-effective options to consider.
