Voltage and Reactive Power Coordination Procedures Sample Clauses

The Voltage and Reactive Power Coordination Procedures clause establishes the protocols for managing and coordinating voltage levels and reactive power within an electrical system. It typically outlines the responsibilities of each party in monitoring, controlling, and adjusting voltage and reactive power flows to maintain system stability and efficiency. For example, it may specify how generators and transmission operators communicate and respond to voltage fluctuations or reactive power imbalances. The core function of this clause is to ensure reliable and efficient operation of the power grid by preventing voltage instability and optimizing power quality.
Voltage and Reactive Power Coordination Procedures. The Parties will utilize the following procedures to coordinate the use of voltage control equipment to maintain a reliable bulk power transmission system voltage profile on their respective systems. 11.2.1 Under normal conditions, each Party will coordinate with the owners of the transmission facilities subject to its control and the Control Areas as necessary and feasible to supply its own reactive load and losses at all load levels. 11.2.2 Voltage schedule coordination is the responsibility of each Party. Generally, the voltage schedule is determined based on conditions in the proximity of generating stations and Extra High Voltage (“EHV”) (defined as 230 KV facilities and above) stations with voltage regulating capabilities. Each Party works with its respective owners of transmission facilities and Control Areas to determine adequate and reliable voltage schedules considering actual and post-contingency conditions. 11.2.3 Each Party will establish voltage limits at critical locations within its own system and exchange this information with the other Party. This information shall include normal high voltage limits, normal low voltage limits, post-contingency emergency high voltage limits and post-contingency emergency low voltage limits, and, shall identify the voltage limit value (if available) at which load shedding will be implemented. 11.2.4 Each Party will maintain awareness of the voltage limits in the other Party’s area (where the EMS Model includes sufficient detail to permit this) and awareness of outages and potential contingencies that could result in violation of those voltage limits. 11.2.5 The Parties will clearly communicate the level of voltage support needed during pre- or post-contingency conditions requiring voltage and reactive power coordination. 11.2.6 Each Party shall maintain a list of actions that are available to be taken when voltage support is necessary to respond to anticipated or prevailing system conditions. 11.2.7 Each calendar quarter the Parties will exchange voltage schedules and shall meet and confer to identify system conditions that could impact the schedules and determine adjustments to the schedules as are consistent with reliability. 11.2.8 In concert with the coordination of Outages addressed in Article VII and the Parties’ respective day-ahead reliability analysis processes, the Parties will coordinate the impact of outages and system conditions on the voltage/reactive profile. Coordination will include the fol...

Voltage and Reactive Power Coordination Procedures. TVA and PJM shall utilize the following procedures to coordinate the use of voltage control equipment to maintain a reliable bulk power transmission system voltage profile on their respective systems. 10.3.1 Under normal conditions, each RC shall coordinate with the Transmission Owners, TOPs, and BAs as necessary and feasible to supply its own reactive load and losses at all load levels. 10.3.2 Voltage schedule coordination is the responsibility of each RC. Generally, the voltage schedule is determined based on conditions in the proximity of generating stations and Extra High Voltage stations with voltage regulating capabilities. Each RC works with its respective Transmission Owners, TOPs, and BAs to determine adequate and reliable voltage schedules considering actual and post-contingency conditions. 10.3.3 Each RC shall establish voltage limits at critical locations within its own transmission system and exchange this information with the other RC. This 10.3.4 Each RC shall maintain awareness of the voltage limits in the other RC’s areas (where the EMS Model includes sufficient detail to permit this) and awareness of outages and potential contingencies that could result in violation of those voltage limits. 10.3.5 The RCs shall clearly communicate the level of voltage support needed during pre- or post-contingency conditions requiring voltage and reactive power coordination. 10.3.6 Each RC shall maintain a list of actions that are available to be taken when voltage support is necessary to respond to anticipated or prevailing transmission system conditions. 10.3.7 The RCs shall exchange voltage schedule information on an annual basis, or more frequently as necessary to reflect actual operations. The RCs shall coordinate as needed to discuss any issues due to the anticipated conditions and determine any actions that may be required in response to voltage concerns. 10.3.8 In conjunction with the coordination of Scheduled Outages addressed in Article Six and the RCs’ respective day-ahead reliability analysis processes, the RCs shall coordinate the impact of outages and transmission system conditions on the voltage/reactive profile. Coordination shall include the following elements: 10.3.8.1 Each RC shall review its forecasted loads, transfers, and all information on available generation and transmission reactive power sources at the beginning of each shift. 10.3.8.2 If no reactive problems are anticipated after the review, each RC shall operate independently,...
