In this paper an efficient algorithm is derived for scheduling real power in systems where the phase angles across lines are not small and, hence, have to be taken into consideration. The approach is based on assigning a cost to the loading on the transmission system. The cost lunction chosen in this paper simplifies the problem of scheduling to a load-flow type problem so that when the solution to the load- flow problem is obtained, the optimal dispatch solution is also automatically obtained. Thus there is no need to alternate between a load-flow step and an optimization step and this results in considerable computational savings.
In this paper we show that any energy (Lyapunov) function to analyze the stability of equilibrium points of systems with transmission losses would, in general, not be a continuous (with respect to transmission losses)...

In this paper we show that any energy (Lyapunov) function to analyze the stability of equilibrium points of systems with transmission losses would, in general, not be a continuous (with respect to transmission losses) deformation of the standard energy function used for a lossless system. This result implies that stability analysis using Lyapunov functions for systems with losses would require Lyapunov functions that are substantially different from the energy function used for lossless systems.
