Real and Reactive Power Control and Primary Frequency Response Sample Clauses

The Real and Reactive Power Control and Primary Frequency Response clause defines the requirements for managing both the amount and quality of electrical power delivered by a generating facility, as well as its ability to respond to changes in grid frequency. This clause typically outlines how the facility must control real (active) power output and reactive power (which supports voltage stability), and mandates that the facility automatically adjusts its output in response to frequency deviations on the grid. By establishing these operational standards, the clause ensures grid reliability and stability, addressing the need for consistent power quality and rapid response to fluctuations in demand or supply.

  • Cloud Computing State Risk and Authorization Management Program (TX-RAMP In accordance with Senate Bill 475, Acts 2021, 87th Leg., R.S., pursuant to Texas Government Code, Section 2054.0593, Contractor acknowledges and agrees that, if providing cloud computing services for System Agency, Contractor must comply with the requirements of the state risk and authorization management program and that System Agency may not enter or renew a contract with Contractor to purchase cloud computing services for the agency that are subject to the state risk and authorization management program unless Contractor demonstrates compliance with program requirements. If providing cloud computing services for System Agency that are subject to the state risk and authorization management program, Contractor certifies it will maintain program compliance and certification throughout the term of the Contract.

  • Primary Frequency Response Developer shall ensure the primary frequency response capability of its Large Generating Facility by installing, maintaining, and operating a functioning governor or equivalent controls. The term “functioning governor or equivalent controls” as used herein shall mean the required hardware and/or software that provides frequency responsive real power control with the ability to sense changes in system frequency and autonomously adjust the Large Generating Facility’s real power output in accordance with the droop and deadband parameters and in the direction needed to correct frequency deviations. Developer is required to install a governor or equivalent controls with the capability of operating: (1) with a maximum 5 percent droop ± 0.036 Hz deadband; or (2) in accordance with the relevant droop, deadband, and timely and sustained response settings from an approved Applicable Reliability Standard providing for equivalent or more stringent parameters. The droop characteristic shall be: (1) based on the nameplate capacity of the Large Generating Facility, and shall be linear in the range of frequencies between 59 and 61 Hz that are outside of the deadband parameter; or (2) based on an approved Applicable Reliability Standard providing for an equivalent or more stringent parameter. The deadband parameter shall be: the range of frequencies above and below nominal (60 Hz) in which the governor or equivalent controls is not expected to adjust the Large Generating Facility’s real power output in response to frequency deviations. The deadband shall be implemented: (1) without a step to the droop curve, that is, once the frequency deviation exceeds the deadband parameter, the expected change in the Large Generating Facility’s real power output in response to frequency deviations shall start from zero and then increase (for under-frequency deviations) or decrease (for over-frequency deviations) linearly in proportion to the magnitude of the frequency deviation; or (2) in accordance with an approved Applicable Reliability Standard providing for an equivalent or more stringent parameter. Developer shall notify NYISO that the primary frequency response capability of the Large Generating Facility has been tested and confirmed during commissioning. Once Developer has synchronized the Large Generating Facility with the New York State Transmission System, Developer shall operate the Large Generating Facility consistent with the provisions specified in Articles 9.5.5.1 and 9.5.5.2 of this Agreement. The primary frequency response requirements contained herein shall apply to both synchronous and non-synchronous Large Generating Facilities.
