Lac-Mégantic: a city looking to the future
5
• The tragic rail disaster in 2013
• The reconstruction of Lac-Mégantic’s downtown area
• A city looking to the future and focusing on innovation and sustainable development
Hydro-Québec | All rights reserved
The Lac-Mégantic microgrid: innovative and original
6
• Connected to Hydro-Québec’s main grid (medium voltage) and able to operate independently (islanding) without the use of a generator
• Including solar panels and both centralized and decentralized batteries to power up to 30 mixed-use buildings (commercial, institutional, residential)
• Equipped with a smart control system for overall islanding management, distributed energy resources (DER) and individual building loads
Hydro-Québec | All rights reserved
Defining the Lac-Mégantic microgrid
• Includes various components such as solar panels, storage devices and energy consumption management tools thanks to an advanced metering and communication system.
• A community-centered initiative.
• Meets local user needs.
• Connected to Hydro-Québec’s main grid and can also operate independently.

Objectives
For Hydro-Québec
Implement the first microgrid in Québec.
Assess DER technologies in a real-life situation.
10
For Lac-Mégantic
Make Lac-Mégantic’s vision of a smart city a reality.
Help increase the city’s appeal as a hub for economic and technological innovation.
Transpose the microgrid model to off-grid systems thus reducing reliance on fossil fuels.
Manage the microgrid’s power demand during winter peak periods by using DERs and load control.

2. Building interventions
19
Residential buildings:
• Home automation equipment
• Batteries based on integration possibilities
Commercial and institutional buildings:
• Improved regulation of HVAC systems
• Batteries and/or photovoltaic solar panels based on integration possibilities
Hydro-Québec | All rights reserved
3. The microgrid’s control system
20
• Islanding control
• Control part of the load included in the perimeter
• Manage the DERs
• Manage demand during winter peak periods
• Must comply with IEEE 2030.7 and IEEE 1547 standards
Hydro-Québec | All rights reserved
Primary required functions of the microgrid’s control system
21
According to IEEE 2030.7:
– Dispatch: for changing function modes and setpoints. The function balances supply and demand of the islanded microgrid and can manage capacity constraints (P, Q) at the microgrid POI to the main grid. This function can use simple rules (automated controls) or optimization to determine setpoints.
– Transitions: receives information about the nature of the transition to be carried out and executes required operations. The four transition modes are unplanned islanding (T1), planned islanding (T2), reconnect (T3), and black start (T4).
These are non-exhaustive descriptions. The details of these functions are included in sections 6.2 and 7.2 of the standard.
