Saudi Arabian Grid Code May 2024

Hz, all Generating Units shall remain in synchronism with the Transmission System for the operating times stated in (2.4.2) to allow the TSP to undertake measures to correct the situation. Each Generating Unit must be capable of contributing to, in a manner satisfactory to the TSP, Frequency and Voltage Control by modulation of Active Power and Reactive Power supplied to the Transmission System or a User System. Chapter 2 - Connection Code The Saudi Arabian Grid Code Updated Version: May 2024 2.5.5.13 The System frequency could vary within the limits given in (2.4.2) and Generating Units are required to be capable of satisfactory operation at any frequency within this range unless the TSP has agreed in the Connection Agreement to the use of any frequency-level relays and/or rate-of-change- of-frequency relays which will trip Generating Unit within this frequency range. 2.5.5.14 Each Synchronous Generating Unit shall be fitted with a fast-acting Speed Governor System to provide Power and Frequency Control under normal operating conditions. The Speed Governor System shall be designed and operated freely to regulate System frequency and shall have adjustable Governor Droop setting within 2% to 8%. The normal set point shall be generally at 5%. Total Governor Deadband (inherent plus intentional) shall be 0.05 Hz or less. The above Droop and Deadband requirement shall apply for an entire combined-cycle Generation facility. Users shall not change frequency or load related control settings of Speed Governors without the prior agreement of the TSP. In islanding situations, the Generating Unit’s Speed Governor System shall also be able to operate at frequency range between 57.5 Hz and 60.2Hz. Each Power Park Module shall be capable of regulating its Active Power under normal operating conditions through modulation of the Active Power as a function of frequency deviations. The Active Power Droop shall be adjustable within 2% and 8%. The normal set point shall be generally at 5%. Total Frequency Regulation Deadband (inherent plus intentional) shall be 0.05 Hz or less. Frequency Regulation from Renewable Resource Generation shall be activated or deactivated automatically following a request from the TSP. Each Renewable Resource Generation shall be capable of regulating its Active Power in the frequency range [60.2Hz, 62.5Hz] through modulation of the Active Power as a function of frequency deviations above 60.2Hz. The Active Power Droop shall be adjustable within 2% and 8%. The normal set point shall be generally at 4%. Output power shall be limited by the Chapter 2 - Connection Code The Saudi Arabian Grid Code Updated Version: May 2024 available output power and the minimum output power of the Generating Unit. The overall requirements for the normal operating range of Active Power in the event of frequency and voltage deviations for a BESS facility at the point of Connection as shown in Figure 2.3 below. The frequency deviations below 57.5 Hz and above 61.5 Hz shall be according to Clause Figure
