Diesel generators (gensets) are often the lowest-cost electric generation for reliable supply in remote microgrids. The development of converter-dominated diesel-backed microgrids requires accurate dynamic modeling to ensure power quality and system stability. Dynamic response derived using original genset system models often does not match those o...

Load forecasting is an important component of power system and resource planning for electrical grids. The adoption of electric vehicles (EVs), behind-the-meter (BTM) solar, and heat pumps will significantly change the amount and variability of loads. Electrification adoption and load forecasting in arctic regions and Alaska is limited. This paper...

The Alaska Railbelt transmission system runs from Fairbanks to Anchorage to Homer and supplies 75% of the state’s population with power. In the near future, this system will experience significant increases in load due to electrification of the transportation and heating sectors. To account for this, several state organizations are working towards...

Diesel electric generators are an inherent part of remote hybrid microgrids found in remote regions of the world that provide primary frequency response (PFR) to restore system frequency during load or generation changes. However, with inverter-based resources (IBR) integration into microgrids, the IBR control provides a fast frequency response (FF...

Converter-based generators are increasingly replacing classical synchronous generation, resulting in significant challenges to the operation and planning of modern power systems. Power electronics (PE)-based equipment, along with non-linear PE-driven loads, introduce time-varying characteristics and fast switching behavior that increases the comple...

In response to national and international carbon reduction goals, renewable energy resources like photovoltaics (PV) and wind, and energy storage technologies like fuel-cells are being extensively integrated in electric grids. All these energy resources require power electronic converters (PECs) to interconnect to the electric grid. These PECs have...

Fundamental shifts in the structure and generation profile of electrical grids are occurring amidst increased demand for resilience. These two simultaneous trends create the need for new planning and operational practices for modern grids that account for the compounding uncertainties inherent in both resilience assessment and increasing contributi...

Resilience in our electrical grid is imperative to the well being of society after events such as natural disasters or cyber attacks. To justify the development of resilience improvements in the grid, metrics are needed to quantify the improvement and cost benefit. These resilience metrics need to consider the inherent uncertainty in the grid, whic...

Distributed energy resources (DERs) are transforming the operation and planning of both distribution and transmission grids. Stability impacts from the increasing generation contribution of DERs have been widely recognized in distribution systems and are emerging in transmission systems. There is a need for the development of transmission hosting c...

A key component of increasing energy access globally is providing rural electrification using off-grid minigrids. Minigrid developers have specific design and planning needs including: (i) equipment sizing and resource allocation, (ii) distribution network layout, and (iii) reliability cost-benefit analysis. Optimization of each aspect is necessary...

Wide-area data and algorithms in large power systems are creating new opportunities for implementation of measurement-based dynamic load modeling techniques.
