“…When the wind speed exceeds the reference wind speed, the protection strategy for a WGS should be designed considering the variation of the electrical characteristics of the WGS with the changes in electrical characteristics of the WGS with the changes in wind speed. The optimal model of the wind power system, whose output was changed by the wind speed, was discussed [20], and the impact of the power system due to a change in wind speed was reviewed [21,22]. Methods for controlling the output of the WGS when the wind speed exceeds the reference were reported [23][24][25][26][27]; the operation of an overspeed relay when the wind speed exceeds the reference velocity was proposed [28][29][30]; and the voltage variation according to the wind speed was discussed [31][32][33].…”

Wind power systems are being integrated increasingly into the power grid because of their large capacity and easy access to the transmission grid. The reliability of wind power plants is very important and the elimination of protective relay's malfunctions is essential to the mitigation of power quality problems due to the frequent starts and stops of high capacity wind generators. In this study, the problem of frequent false operations of the protective relays are analyzed using real data as line voltages, line currents, and wind speed. A new re-coordination of the overcurrent relay (OCR) based on the wind speed is proposed to avoid frequent operations of relays and tested for a grid-connected wind farm. This study verifies that the false actions by the OCRs that are not accompanied by actual electrical faults in the power grid or wind power system can be solved by the appropriate re-coordination of the OCR.

“…As increasing penetration of wind power, wind power brought great threaten to the system stability because of fluctuation and uncertainty of the wind. Especially, the great change of wind power in short time which is called as a ramp is very harmful to the power grid [2][3][4][5][6][7]. In order to get a reasonable and efficient prediction model to forecast ramp events, each country has done a lot of research.…”

Abstract. Description of probability distribution characteristics of wind power ramp events is always a challenge in grid-connected wind power operation analysis. In this paper, a moving ratio based approach of wind power ramp events is introduced and an probability model is described for the wind ramp events. The proposed model is useful to estimate the relationship between power ramp events and the variability of the wind power. The proposed model is able to satisfactorily approximate the actual distribution of wind power ramp events . It is shown that the linear difference based ramp distribution can be calculated using the proposed moving ratio based approach. The proposed model can be an effective tool in planning for wind power ramp control.

Aging network assets, forced and unforced outages, and the way the networks are operated in a deregulated market are of significant concerns to integrate large wind farms in a distribution network. In many cases, the constrained network capacity is a potential barrier to the large-scale integration of wind power. This paper probabilistically assesses the steady-state security in a distribution network in the presence of large wind farms. The approach incorporates active distribution network operating conditions, including intermittent power outputs, random outages, demand fluctuations, and dynamic interactions and exchanges, and then assesses the steady state security using Monte Carlo simulation. A case study is performed by integrating large wind farms into a distribution network. The results suggest that intermittent outputs of large wind farms in a distribution network can impact the steady-state security considerably. However, the level of impact of wind farms does not necessarily correlate with the installed capacity of them.
