Aklavik Variable Speed Diesel

Variable Speed Diesel and Natural Gas Generation for 100% Renewables Integration

Today’s sophisticated microgrids are challenged by operating with 125-year-old synchronous generation technology. Complex systems, controls, and storage are required to maintain grid stability when integrating high penetration renewables. Using power electronics to enable Variable Speed Generation (VSG) optimizes efficiency by allowing the generator’s engine to operate at optimal speeds for any load and maintains microgrid stability at any renewable penetration by producing power through a back to back converter platform.

This presentation discusses technology advances that eliminate the need for storage to provide grid stability for high penetration renewables, therefore significantly lowering the levelized cost of energy.

We will discuss the results of the Waterloo Institute for Sustainable Energy report, “Feasibility of Variable Speed Generators for Canadian Arctic Communities”. The report demonstrates how the use of converter-based generation significantly lowers emissions, fuel consumption and provides the lowest LCOE for remote northern community renewable integration.

We will also review the results from a recent installation of a 590kW VSG installation in the community of Aklavik Northwest Territories Canada.

  • Understand the benefits of decoupling Engine speed from frequency
  • How converter-based generation enables high penetration renewables
  • Understand the potential for high transient response and sub 10 seconds for natural gas generators
  • Understand how variable speed generation reduces engine damage and maintenance costs
