Results from two practical and fast methods to estimate systems' Maximum Loading Point (MLP) using Phasor Measurement Units (PMUs) are used in this paper as initial values for a robust and very efficient method that takes advantage of the geometric characteristics of the maximum loading hyperplane and uses the load flow with step size optimization (LFSSO) technique to estimate the system's proximity...
In this work a robust load flow method based on the Synthetic Dynamics Power Flow (SDPF) and on the Load Flow with Step Size Optimization (LFSSO) is presented. The original approach of SDPF uses variable step size implicit integration to solve the resulting differential-algebraic equations that represents the load flow problem. The proposed method Synthetic Dynamics Power Flow with Optimal Multiplier...
A practical and fast method for computing power systems' maximum loading point (MLP) using the load flow with step size optimization (LFSSO) technique is presented in this paper. The method is based on successive calculations of operating points in the infeasible region of the parameter space, from a large loading (larger than the actual maximum) down to the actual maximum loading, by using a load...
In this work, the performances of robust load flow methods are compared, in special when applied to ill-conditioned systems. In such cases, the iterative process may diverge or oscillate when standard Newton Raphson (SNR) based load flow calculation methods are used. Some known approaches to solve these systems are the Load Flow with Step Size Optimization (LFSSO) and Continuation Power Flow (CPF)...
In this paper a fast, practical maximum loading point (MLP) calculation method is presented. The calculation process is based on the properties of the normal vector to the feasibility boundary computed close to MLP, which is calculated through a load flow method with step size optimization (LFSSO). Moreover, a practical procedure is added to the overall calculation process to include the operator's...
