Power flow modeling/calculation for power systems with Dynamic Flow Controller

2008 IEEE Vehicle Power and Propulsion Conference, 2008
This paper presents a new procedure for power flow calculation of power systems in presence of dynamic flow controller (DFC) which is a new member of FACTS controllers. The focus of the paper is to explore how to systematically extend and modify Newton-Raphson power flow method to include DFC.

Power Flow Calculation Method for Islanded Power Network

2009 Asia-Pacific Power and Energy Engineering Conference, 2009
In the practical power system operation, sometimes, some reasons will lead to local power network splitting, generate islanded power network operating. In order to ensure islanded power network operation safety and stability, it is urgently need to know power flow distribution for islanded power network.

Calculation of multiple power flow solutions with the Krawczyk method

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003
This paper proposes an interval-analysis based power flow computation for calculating multiple power flow solutions in power systems. The interval technique provides more reliable solution with the upper and lower bounds. This paper makes use of the Krawczyk method to evaluate the interval power flow solution.

Dynamic power flow calculation method of power system with wind power

2015 5th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2015
High penetration of renewable energy nowadays makes it necessary to take wind power plants and solar power plants into consideration when calculating dynamic power flow. The paper mainly focuses on the approach to deal with wind turbine in power flow calculation and the power-frequency characteristics of it after attaching it to power system.

Calculation of power flow and bus voltages

Electrical Engineering, 1935
The method for calculation of power flow and bus voltages in a-c networks described in this paper is based upon Kirchhoff's laws, and is novel mainly in that the power losses are lumped at the network terminals in determining power flow. The effect of circuit shunt capacitance is included.

Optimal power flow calculation of power system with wind farms

2011 IEEE Power and Energy Society General Meeting, 2011
With the rapid development of wind power generation, integrated wind farms will exert a growing influence in the economic operation of power system. This paper build an OPF model with wind farms which includes the stable model of wind generator and the added up spinning reserve and down spinning reserve caused by the uncertainty of wind power.

Quasi-Newton Methods for Power Flow Calculation

2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE), 2020
In this work, we compared the performance of the ordinary Newton-Raphson method for calculating power flows against three quasi-Newton methods: chord, “good” and “bad” Broyden's methods. First, we illustrated compared the performance of each method on systems of equations of different sizes. Secondly, we compared these methods on power flow calculation

Power flow calculation method of large shipboard power system

Journal of Marine Science and Application, 2010
The effect of line voltage drop is considered larger on loads, especially on asynchronous motor, transformers and other non-linear load parameters in power system of large ships. A novel power flow method based on improved node voltage method is proposed, and a typical ship power system, which has 2 power stations and 10 nodes, with closed-loop design ...
