Project Experience

COL Chinook 181S DER Solar Interconnection Engineering Study

Date:

Mar 2022 - Oct 2022

Client:

City of Lethbridge

Midgard was retained by the Electric Utility of City of Lethbridge to serve as the Study Consultant for its 8.75 MW Solar project located in Alberta. In this role, Midgard collaborated with AESO on behalf of NU-E Corp to conduct various connection studies for the project. These studies encompassed power flow analysis, voltage stability analysis, and short-circuit analysis.Power flow analysis was conducted for both the Summer Peak (SP) and Winter Peak (WP) scenarios, both pre- and post-Project, to assess the impact of the project's connection on the Alberta Interconnected Electric System (AIES). Voltage stability analysis was specifically performed for the WP post-Project scenario to identify any potential violations of voltage stability criteria. Additionally, short-circuit analysis was carried out for the WP pre-Project scenario, as well as the WP and WP post-Project scenarios, to determine short-circuit levels in the project's vicinity.
