Discuss the concept of load shedding in power systems. Under what circumstances is load shedding implemented, and what are the consequences of load shedding for consumers and the grid?

Borduria Generation owns three generating units that have the following cost functions: Unit A: 15 + 1.4 PA + 0.04 P2 A $/h Unit B: 25 + 1.6 PB + 0.05 P2 B $/h Unit C: 20 + 1.8 PC + 0.02 P2 C $/h How should these units be dispatched if Borduria Generation must supply a load of 350 MW at minimum cost?

How do renewable energy sources like solar and wind power integrate into the existing power system, and what challenges does this integration pose?

The voltage regulation of an alternator having 0.75 leading p.f. load, no-load induced e.m.f. of 2400V and rated terminal voltage of 3000V is............... percent. *

A generating station has a maximum capacity of 100 kW and costs $300,000. The annual fixed charges are 12% of the cost of the generating station consisting of 5% interest, 5% depreciation and 2% taxes. Find the fixed charges per kWh generated if load factor is (a) 100% and (b) 25%.

Q20. The section bus-bars A and B as shown in Figure B5 are linked by a bus-bar reactors each rated at 5000 kVA with 10% reactance. On bus-bar A, there are two generators each of 10,000 kVA with 10% reactance and on B two generators each of 8000 kVA with 12 % reactance. Find the Current and MVA that fed into a dead short circuit between all phases on B with bus-bar reactor in the circuit.
