How is net tie deviation from schedule calculated?

• A. NIS + NIA
• B. NIA - NIS
• C. NIS / NIA
• D. 10B (FA - FS)

Answer: (B)

The correct method to calculate net tie deviation from schedule is determined by the difference between the actual net input to the system (NIA) and the net interchange schedule (NIS). Net interchange schedule (NIS) represents the planned or scheduled exchange of power between interconnected systems, while net input actual (NIA) indicates the actual amount of power that has been received or injected into the system. By subtracting the net interchange schedule from the net input actual, you obtain the net tie deviation, which reflects how much the actual interchange deviates from what was originally scheduled. This calculation is critical for system operators to understand the discrepancies in power flows, allowing for better control and adjustment of power delivery and consumption across networks. The focus is on ensuring that the actual input aligns closely with the scheduled interchange to maintain system reliability and operational stability.
