Grid Interconnection

This guideline is primarily intended to provide an overview of the application process involved in becoming a distributed generator. If a prospective power plant owner plans to generate electric energy and the power plant capacity rating is less than one MW, the applicant may proceed without filing an application with the Alberta Utilities Commission (AUC) if the following three requirements are met: ? No person is directly and adversely affected. ? The power plant complies with AUC Rule 012: Noise Control (AUC Rule 012). ? There is no effect on the environment.

The scope of this document is to provide guidelines for consistant and standard applications for voltage and power quality requirements on or connected to HOL’s distribution system. Normally voltage limits, voltage distortion, and current distortion are measured at the customer’s Point of Supply as per HOL document ECS0012. This document does not cover the following power quality issues: • Voltage control when the Independent Electrical System Operator (IESO) has declared a voltage reduction or an electrical system emergency; • Non-standard conditions such as a force majeure (e.g.

This guideline is intended to assist the customer in understanding the connection process that results in connection of the customer's generation facility to Hydro Ottwwa's distribution network. This guideline does not provide all the details of costs or responsibilities that the customer may assume; such details will be evaluated for each specific request.

These requirements cover bidirectional electric vehicle charging equipment that charge electric vehicles from an electric power system and also include functionality to export power from the electric vehicle to an electric power system. When commanded, the bidirectional charging equipment exports electric power from the electric vehicle stored energy supply to the electric power system (EPS) to supply power to common loads.

Third parties must use certified equipment (both behind the meter and on the distribution grid) when attempting to interconnect new components to the grid. Certified equipment is equipment that has passed through rigorous certification testing procedures done by Nationally Recognized Testing Laboratories (NRTLs); UL is one such example. NRTLs create testing procedures for equipment that verify equipment functionality and safety to pre-set testing standards created by nationally recognized engineering groups such as IEEE.

The standard specifies the general requirements for the design and the implementation of micro grids used in decentralized rural electrification to ensure the safety of persons and property and their satisfactory operation according to the scheduled use.

NFPA 791 covers recommended procedures for evaluating unlabeled electrical equipment for compliance with nationally recognized standards. Criteria provide guidance to third-party field evaluation bodies (FEBs) on how to perform evaluations of unlabeled electrical equipment in a consistent and reliable manner, thus assisting regulating authorities who make product and related installation approval decisions and facilitating acceptance of the results. Specific areas covered include pre-site preparation, construction inspection, electrical testing, and reporting, and documentation.

1.1 These requirements cover Wind Turbine Converter (WTC) products and assemblies. Some of the features and functions of these products include but are not limited to, generation of real and reactive power in parallel with the electric power system, EPS (electric utility grid), supplying power in a standalone operational mode, multiple mode operation, and bidirectional power flow operation with the EPS.

This Standard specifies the electrical installation requirements for inverter energy systems and grid protection devices with ratings up to 10 kVA for single-phase units, or up to 30 kVA for three-phase units, for the injection of electric power through an electrical installation to the electricity distribution network. NOTES: 1 Although this Standard does not apply to larger systems, similar principles can be used for the installation of such systems. 2 This Standard does not cover detailed installation requirements for the energy source(s) and its associated wiring.

The document describes switchgear as a general term covering switching, interrupting, control, metering, protective, and regulating devices and assemblies of these devices with their associated interconnections, accessories, and supporting structures and provides for the basic operation, protection, inspection, maintenance, and testing of various types of switchgear used in applications of at least 600V.
