Discussion of relations between equal consumed energy increase ratio law & equal network loss increase ratio law and optimal power flow;

Practical researches of paralleled optimal power flow algorithm based on subarea division of the power system;

An approach to congestion problem is presented,which combines OPF(Optimal Power Flow) and CPF(Continuation Power Flow) and maintains the system operating within voltage security margin.

The allocation methods based on Aumann-Shapley use discrete intogration method and need to solve the OPF for many times, they are not suitable for large scale system application.

This model bases on the OPF including the main aspects to be considered in designing the tender , such as , notice in advance, power factor of load .

An optimal power flow (OPF) technique based on the sequential quadratic programming (SQP) and the enumeration method for power system reliability analysis are utilized to calculate total transfer capabilities (TTCs) of interconnected power systems and their probability distributions.

To solve the problem, a novel method based on optimal power flow (OPF) was proposed for calculating the TTC.

In the paper the constrained load flow is calculated by optimal power flow (OPF) approach in which the sequential quadratic programming (SQP) method is applied, and in the OPF calculation the active power output, the reactive power output and the voltage of generators are selected to be the control v.
