Power flow for planning
Multiple scenario analysis
Peak load scenario
Does one need an off peak load scenario as well?
Other drivers for investment planning
Quality of service (duration and frequency of interruptions, voltage sags, )
System security and robustness
Capture of renewables
Scenario generation
Output analysis
Power flow as the working horse of system analysis
Power flow for reliability assessment
Load, equipment, resource availability as random quantities
Sampling techniques and Monte Carlo
Importance of autocorrelation and cross-correlation for sampling
Probabilistic power flow and radial networks
Simultaneity factor
Kirchhoff for random currents and random powers
Currents based on mu+2*sigma (95% certainty)
The apparent non-compliance with KCL
Example for a case of independent loads
