BRAIN LOAD DESPATCH CENTRE
Controls the Body Function and keeps the critical parameters like temp, BP, Sugar level etc within limits
Controls the Power System and keeps critical parameters like Voltage, frequency, MW, MVAR etc within limits
Uses sensors like Eyes Ears, Skin, Tongue, Nose for data collection
Uses Sensors like Transducers, Relays, RTUs etc. for data collection
Uses Nervous system for communication
Uses PLCC, Fibre Optics, Microwave for communication
MAIN ARTERIES TRANSMISSION
Pumps blood from Heart to the Sub-Arteries throughout the Body
Transfers Power from Generation to Sub-transmission throughout the Country
SUB- ARTERIES
SUB- TRANSMISSION
Deliver Blood from Main Arteries to each and every Body Part
Deliver Power from Bulk Transmission points to every part of the Grid.
CAPILLARIES
DISTRIBUTION
Actual extraction of oxygen from blood takes place
Actual consumption of electricity occurs

AVAILABILITY BASED TARIFF
(A) CAPACITY CHARGE
(B) ENERGY CHARGE
(C) ADJUSTMENT FOR DEVIATIONS (U I CHARGE)
Where
(A) = a function of the Ex-Bus MW availability of Power Plant for the day declared before the day starts x SEB’s % share
(B) = MWh for the day as per Ex-Bus drawal schedule for the SEB finalised before the day starts x Energy charge rate
(C) = Σ (Actual energy interchange in a 15 minute time block – scheduled energy interchange for the time block) x UI rate for the time block
TOTAL PAYMENT FOR THE DAY = (A) + (B) ± (C)
