Saudi Arabian Grid Code May 2024

Overview of the Dispatch Process Instructions accepted by Generator? TSP issues Dispatch Instructions to Generator Dispatch Instructions to Synchronize/ Desynchronize Generator Synchronizes Active/Reactive Power Dispatch Operating Mode Dispatch Parameter changes Instructions for Demand Reduction, Disconnection, and Restoration The entity discusses with TSP, and TSP issues new Instructions TSP revises Instructions, if possible Generator discusses and clarifies to TSP TSP issues Dispatch Instructions to Distribution Entities/ Directly-connected Customers. System Emergency Conditions Additional Instructions The entity takes action Instructions for Load Transfer between Connection Points Instructions for Switching in Load Shedding Scheme The entity achieves target Any unforeseen problems? Informs the TSP Generator achieves target Generator complies with Instructions Yes Yes Yes NO NO NO Can Generator Synchronize within10 minutes? Chapter 5 - Scheduling and Dispatch Code The Saudi Arabian Grid Code Updated Version: May 2024 APPENDIX A5.1: Generating Block/Unit Declaration A5.1.1 Availability Notice (i) Generating Availability, (start time and date). (ii) Generating Unit regime unavailability, (day, start time, end time). (iii) Generating Unit initial conditions (time required for Notice to Synchronize and from Start-up to Synchronize). (iv) Maximum Generation increase in output above declared Availability. (v) Any changes to Primary Response and Secondary Response characteristics. A5.1.2 Scheduling and Dispatch Parameters (i) Generating Unit inflexibility (inflexibility description, start date and time, end date and time, MW); (ii) Generating Unit Synchronizing intervals (hot time interval, off-load time interval); (iii) Station Generating Unit De-Synchronizing intervals; (iv) Generating Unit basic data: (a) Minimum Generation; (b) Minimum Shutdown time; (v) Generating Unit duty-cycle limitation; (vi) Generating Unit minimum on time; (vii) Generating Unit Synchronizing MW; (viii) Generating Unit Synchronizing groups; (ix) Generating Unit run-up rates with MW breakpoints; (x) Generating Unit run-down rates with MW breakpoints; (xi) Generating Unit loading rates covering the range from Minimum Generation to Net Dependable Power Capacity; (xii) Generating Unit de-loading rates covering the range from Net Dependable Power Capacity to Minimum Generation. Chapter 6 - Data and Information Exchange Code The Saudi Arabian Grid Code Updated Version: May 2024 CHAPTER 6 DATA AND INFORMATION EXCHANGE CODE Introduction 6.1.1 The proper and timely exchange of data and information between the TSP and Users is critical for ensuring non-discriminatory access to the Transmission System and the safe and reliable provision of Transmission services. This chapter, therefore, sets out the obligations and responsibilities of the TSP and Users in relation to the supply of data and information to each other, and also lists the various categories of data and information to be exchanged between the TSP and the Users. 6.1.2 The data which is specified in different chapters of the Grid Code are collated here in this chapter. The relevant chapters also specify the procedures and timings for the supply of the requisite data. 6.1.3 The various chapters of the Grid Code also specify the information that the TSP will supply to Users. This information is summarized in a single schedule in this chapter. 6.1.4 The data listed in the various chapters of the Grid Code contain only the typical range of data which may be required by the TSP. The actual data required will be advised by the TSP at the time of assessment of the User application for new, or modification of an existing, Connection.
