Improved Area Interchange Control Method for Use with any Numerical Technique

One of the main causes of poor convergence of the load flow solution incorporating standard area interchange control is the artificial adjustment of real power generation at certain area "regulating buses" between iterations of power flow. A more realistic method of determining real power generation at these buses is proposed using linear network theory. This allows load flow calculations including area control with practically the same convergence rate as in studies tnwhich aea contol is excluded.
