polycost
- polycost(gencost, Pg, der)
polycost()
- Evaluates polynomial generator cost & derivatives.F = POLYCOST(GENCOST, PG) returns the vector of costs evaluated at PG DF = POLYCOST(GENCOST, PG, 1) returns the vector of first derivatives of costs evaluated at PG D2F = POLYCOST(GENCOST, PG, 2) returns the vector of second derivatives of costs evaluated at PG GENCOST must contain only polynomial costs PG is in MW, not p.u. (works for QG too) This is a more effecient implementation that what can be done with MATLAB's built-in POLYVAL and POLYDER functions.
