The ordinary power flow or load flow problem is stated by specifying the loads in megawatts and megavars to be supplied at certain nodes or busbars of a transmission system and by the generated powers and the voltage magnitudes at the remaining nodes of this system together with a complete topological description of the system including its impedances.

Optimal Power Flow By Newton Approach
IEEE Transactions on Power Apparatus and Systems, 1984The classical optimal power flow problem with a nonseparable objective function can be solved by an explicit Newton approach. Efficient, robust solutions can be obtained for problems of any practical size or kind. Solution effort is approximately proportional to network size, and is relatively independent of the number of controls or binding ...

Intelligent optimization techniques for optimal power flow using Interline Power Flow Controller
2010 IEEE International Conference on Power and Energy, 2010In this paper the control parameters of voltage source converters used in Interline Power Flow Controller (IPFC) are designed to realize optimal power flow in a power system with modified Newton-Raphson method. The optimal control parameters are derived to minimize the transmission line losses employing three intelligent optimization techniques, namely

Optimal Power Flow With Complementarity Constraints
IEEE Transactions on Power Systems, 2005This paper proposes a mathematical program with complementarity constraints to better model the relationship between the base, or current, operating point and the maximum loading point in a power system when solving maximum loading problems.

A new optimal harmonic power flow (OHPF) method is proposed in this paper. This new OHPF is designed to minimize the MW losses and the total harmonic voltage distortion while satisfying the power flow equations, harmonic power flow equations, security constraints and harmonic standard, etc. A two-level algorithm is used to solve the problem: the master

This chapter describes the optimal power flow problem. Section 6.1 provides the background of the OPF problem and justifies the need for numerical methods. Section 6.2 provides a general nonlinear programming model for the OPF problem. A variety of examples are also provided in this section. Section 6.3 describes two solver methods for tackling the OPF
