Power system frequency and voltage control are of paramount importance to maintain the stability and reliability of the emerging smart grid. With the large-scale deployment of power electronic converter (PEC) interfaced renewable power generation (e.g., wind generation and solar-photovoltaic), the conventional strategies to control and maintain system frequency and voltage are becoming inadequate. Therefore, new strategies should be deployed in power grids to maintain frequency and voltage within acceptable levels stipulated in grid codes. This webinar will cover frequency control techniques, such as droop control, synthetic inertia control and hybrid control schemes, that can be used in PEC-interfaced sources. Furthermore, voltage stability aspects with high-share of PEC-interfaced renewables (short-term and long-term voltage stability), and voltage control schemes, such as Volt-Var and Volt-Watt functions will be covered with example case studies. Finally, this webinar will shed light on various technologies (battery storage, synchronous condensers, virtual power plants) available for frequency and voltage control together with the deployment aspects and performance limitations.

Increasingly, digitalization is a permanent aspect of today’s operations, and cybersecurity is the linchpin to a safe and secure transition. But most of the time, the shift toward digitalization outpaces the cyber resilience required to effectively manage risks to the business. Consequence-driven, cyber-informed engineering (CCE) enhances risk assessment for cybersecurity by combining first-principles thinking with engineering.

This webinar will:

  1. Discuss the importance of applying engineering to cybersecurity and vice versa
  2. Present the approach of CCE
  3. Discuss the application of CCE in smart grid

This webinar is based on an earlier SmartGrid e-newsletter article, “Active Damping With Energy Storage to Improve Power System Frequency Stability”, This earlier article outlined how appropriately designed energy storage (ES) systems can offset the negative power system impacts of reduced inertia (H, MW-s), as traditional rotating machines are offset by inverter based resources including PV.

In this webinar, the authors focus on two specific areas, 1) underlying control design concept for using ES with advanced power electronics with advanced grid sensing (e.g. PMU’s) to damp power system oscillations, 2) examples of early energy storage systems that have demonstrated that appropriately designed ES systems can and have supported power system frequency stability.

The electric grid as it stands today was designed for an exclusively one-way powerflow from bulk generation facilities, encompassing plants from base load support to peaker plants, to end-users. In this model, instantaneous demand changes were accommodated through small, temporary frequency adjustments, quickly reversed through appropriate management of bulk generation output.

Distributed Energy Resources (DER) present a substantial challenge to the traditional model. Not only can powerflows reverse during peak for several hours each day, the output of these new sources can also change much more quickly, potentially leading to much more dramatic demand swings for bulk generation than the current system can accommodate.

This presentation will present a framework for analyzing new requirements for the grid during the phases of the DER roll out and discuss how systems and capabilities have to change to ensure safe and reliable power delivery as the grid undergoes its most fundamental technical and business change since its creation.
