Pertinent

This Standard provides a method of presenting technical information relating to the selection of storage batteries for photovoltaic systems and to the precision of that information.
Note: A distinguishing feature of photovoltaic (PV) power systems is the unpredictability and limitation on the amount of charging power available and hence on the charge-d ischarge cycles imposed on the storage battery.
1.2
This Standard includes procedures designed to verify the capacity, efficiency, and longevity of storage batteries.

The purpose of this standard is to develop industry-wide requirements including methods and procedures for the control of battery room and enclosure environments. This includes adequate ventilation of battery-generated gases, the dissipation of battery-generated head, the control of room and enclosure temperature, the management of battery electrolyte spills, and in general the control of any contaminates within the battery room or enclosure.

1.1 This Standard applies to uninterruptible power supplies (UPS). The primary function of the UPS covered by this Standard is to ensure continuity of an alternating power source. The uninterruptible power supplies can also serve to improve the quality of the power source by keeping it within specified characteristics. 1.2 This Standard is applicable to movable, stationary, fixed, and built-in UPS for distribution systems up to and including 600 V ac.

This standard specifies the type, production, and commissioning tests that shall be performed to demonstrate that the interconnection functions and equipment of a distributed resource (DR) conform to IEEE Standard P1547; Interconnection equipment that connects distributed resources (DR) to an electric power system (EPS) must meet the requirements specified in IEEE Standard P1547. Standardized test procedures are necessary to establish and verify compliance with those requirements.

IEEE Std 1547.2-2008 provides application details to support the understanding of IEEE Std 1547-2003 and is intended to serve DR owners and operators as well as area EPS staff. It provides technical background, application details and guidance, requirements rationale, schematics, and examples to facilitate the use of IEEE std 1547-2003. This guide addresses some topics that are related to DR project implementation to enhance user understanding of how IEEE Std 1547-2003 may relate.

This document provides guidelines for monitoring, information exchange, and control for distributed resources (DR) interconnected with electric power systems (EPS)

Recommendations and guidance for distributed resources (DR) interconnected on the distribution secondary networks, including both spot networks and grid networks, are provided. This document gives an overview of distribution secondary network systems design, components, and operation; describes considerations for interconnecting DR with networks; and provides potential solutions for the interconnection of DR on network distribution systems. IEEE Std 1547.6-2011 is part of the IEEE 1547™ series of standards.

IEEE Std 1547.7™ is part of the IEEE 1547™ series of standards. Whereas IEEE Std 1547™-2003 provides mandatory requirements for the interconnection of distributed resources (DR) with electric power systems (EPS), this guide does not presume the interconnection is IEEE 1547™ compliant. Further, this guide does not interpret IEEE Std 1547™ or other standards in the IEEE 1547™ series, and this guide does not provide additional requirements or recommended practices related to the other IEEE 1547™ documents.

Background on light flicker caused by fluctuations in power demands of variable loads is presented in this recommended practice. A flicker measurement method is presented using a meter that is completely described in IEC 61000-4-15. The short-term (Pst) and long-term (Plt) flicker indices used for the analysis of flicker data are defined. Flicker limits for various voltage levels are presented. An assessment procedure for evaluating flicker compliance against emission limits is described.
