“…Furthermore, for the hub-to-hub links it is assumed that they all are of 1.256 GW rated capacity and to the market model 1.2 GW Net Transfer Capacity (NTC) per circuit is given. For the offshore grid load flow calculations the DC grid model presented in [18] is used and by running load flow calculations for each hour of the simulated year, the risks of overload are assessed according to the methodology presented in [12]. Next, the NTCs given to the market model for all the overloaded hub-to-hub links are reduced in equal steps until no more overloads occur.…”

“…Only N situations were analysed as it was assumed that the offshore grid does not have to be N-1 secure. The risk of overload during N situation (RO N,i ) for each of the hub-to-hub links is determined under all cases as described in [12] using (1) from the Appendix section. Table 2 illustrates the risks of overload and the criteria for the N situation for each of the three grid topologies.…”

This work provides a method for combined planning of a possible offshore grid in the North Sea together with the onshore grid, for a high renewable energy scenario in the year 2030. The analysis is done with the help of both market simulations and load flow calculations. The round-the-year security analysis is used to evaluate different offshore grid structures and the interdependencies that exist between grid structure and available capacity for market transactions. Grid security, grid utilization factors, operating costs (fuel and emissions) and wind curtailment are considered in the assessment. Furthermore, the same round-the-year security analysis is used to investigate the effects of the offshore grid on the security of the Dutch onshore grid. A sensitivity analysis to the presence of the German North-South HVDC corridors on the security of the Dutch grid is also performed.

Increasing the wind energy penetration in a power system presents some technical challenges to the transmission expansion planning (TEP). In the first stage of TEP, the transmission bottlenecks should be determined and ranked via security assessment. The high penetration of wind energy means a large number of wind farms exist in various geographic areas. It is found that there is a correlation between the wind speed series of different farms. Therefore, integration of the correlated wind farms into security assessment is addressed in this study. Hence, a new model of wind speed prediction is presented based on the correlated autoregressive moving average time series. The copula functions are used to make the predefined correlation among wind speed series. Here a linear correlation using a Gaussian copula is implemented. Then, the risk-based security assessment is performed using the proposed sequential time simulation. The proposed process is applied to the modified IEEE 39-bus test system which comprises 15 wind farms. Then, the transmission bottlenecks are identified and ranked regarding their overload risks. Finally, the impacts of the wind farms correlation on the risk index are investigated and those contingencies which impose the highest influence on this risk are identified.
