Power flow calculation for power system including offshore wind farm

Node modeling of wind farm in power flow calculation is an issue which must be solved. This paper described mathematical model of asynchronous generator which be used widely, elaborated mathematical model and calculation process of several wind farm node models in power flow calculation, discussed calculation speed and accuracy of every model and pointed out that under the premise of high level calculation speed, how to add wake effect to power flow calculation process will be a significant direction for wind farm modeling studies.

The Real

Steady-state power flow calculation belongs to power system steady-state analysis, and the data used in calculation should be steady-state data. However, the existing SCADA system hasnt distinguished the transient data from the steady-state data. The real-time measured data reflect the dynamic electric power system. It is the right reason for not all of the real-time measured power can be used for power flow calculation. In another word, it causes the matching problem between measured data and power flow calculations. Based on the current situation of information collection system, the characteristics of the measured data had been analyzed in this paper. And an effective acquisition method for steady-state measured data is proposed on the theoretical basis of the law of large numbers. It uses the average value of the measured data that in the same load state to approximate the steady-state true value in one period. And the steady-state data can be used in power flow calculation. The simulation results show that the method proposed in this paper ensures the accuracy and reliability of power flow calculation.
