This paper extends the application of probabilistic peak-shaving technique used for simulating limited-energy units, LEUs, probabilistically within the framework of equivalent load duration curve, ELDC method. The extension of the application is within the framework of frequency and duration, FD, method. The technique proposed is independent of the ELDC and FD representations. The application of the technique is demonstrated with the help of a hand calculation example. An efficient algorithm is also presented to simulate multiple LEUs probabilistically, for different hydrological conditions, in a generation mix of hydrothermal units within ELDC and FD framework. The algorithm overcomes the ordering problem of LEUs and requires no deconvolutions of ELDCs and load transition frequency equations.
