Grid Interconnection

Description: Considered in this guide are the components of both the ac and dc systems and the provided guidelines and recommendations for designing the appropriate systems for the substation under consideration. This guide includes the low-voltage auxiliary systems from the source(s) to the distribution point(s). Reliability requirements and load characteristics are discussed and distribution methods are recommended.

Scope:
This standard defines the method for determining load unbalance emission limits for customers connecting to, or requesting connection to BC Hydro's public medium-voltage (MV) distribution network. It also describes the assessment process for verifying compliance with prescribed load unbalance emission limits.
Application:
Q4 is intended for application by distribution planning engineers, regionalengineers, designers and power quality engineers for:

IEEE Std 2030 provides alternative approaches and best practices for achieving smart grid interoperability. It is the first all-encompassing IEEE standard on smart grid interoperability providing a roadmap directed at establishing the framework in developing an IEEE national and international body of standards based on cross-cutting technical disciplines in power applications and information exchange and control through communications.

PURPOSE AND APPLICATION
This standard defines the minimum requirements and
technical specifications for the interconnection of
distributed generation to the Hydro-Québec medium-vo
ltage (MV) distribution system. The standard is
also applicable when an existing generati
ng station must be modified or upgraded.
Given the various means of generation, modes of
interconnection and potential system constraints,
Hydro-Québec may define certain specific requirements at the time each case is reviewed.

1 PURPOSE AND FIELD OF APPLICATION
This standard defines the minimum technical requirements and specifications for connecting single-phase or three-phase decentralized generation to the Hydro-Québec low voltage (LV) distribution network. It also applies when such a plant is modified or repaired. The plants covered by this document have the following characteristics:
• maximum rated three-phase power of 600 kVA;

1 PURPOSE AND FIELD OF APPLICATION
This standard defines the minimum technical requirements and specifications for the connection of
decentralized production without power injection to the low voltage (LV) distribution network and
medium voltage (MV) from Hydro-Québec. This standard applies to all new installations as well as to
those that are subject to modification or repair.
The plants covered by this document must not, under any circumstances, inject current, energy or

1 PURPOSE AND FIELD OF APPLICATION
This standard defines the minimum technical requirements and specifications for connecting the
decentralized generation to the Hydro-Québec low voltage (LV) distribution network. Centrals
covered by this document have the following characteristics:
• single-phase maximum nominal power of 20 kW;
• maximum nominal three-phase power of 50 kW;
• use of inverters certified according to section 15 of standard CSA C22.2 no 107.1-01.

1. PURPOSE AND FIELD OF APPLICATION
This standard defines the minimum technical requirements and specifications for the temporary paralleling of emergency generation equipment to the Hydro-Québec distribution network.
This standard applies to all new installations as well as those that are modified or repaired.
