A novel sensitive based approach to ATC enhancement in wind power integrated transmission system

Abstract

Available transfer capability (ATC) plays an important role for both buyers and suppliers in the deregulated power system. As the integration of renewable energy sources is taking place very quickly in the system. It is not suggested to place wind generation (WG) at any point of the system. In this paper, the optimal location of buses for WG using a novel sensitive based formula is proposed. The zones are formed using the transmission congestion distribution factor (TCDF) values. The average transmission congestion distribution factor (ATCDF) is used to locate the optimal point of the system. When the WG is integrated into the system its obvious ATC increases but at which point the ATC values will be more is considered as the main objective. The WG is placed at every bus in the zone created by the TCDF value and the ATC value is calculated. The test is performed on the IEEE-30 bus system in MATLAB coding environment. The comparison result shows the ATC value enhances more when the WG is placed according to the proposed method. The proposed method also helps to find multiple locations for WG installation according to ATCDF value. Highlights Average TCDF value is proposed to find the optimal bus location for getting more ATC value. Integration of WG according to highest ATCDF value in the system. Comparison of ATC obtain from the integration of WG at different buses in sensitive zones. Validation of a proposed method by comparing the ATC value obtain from integrating WG at different buses. The optimal bus location based on the ATCDF value gave enhance ATC value compare to the other bus location. ATCDF value helps in finding the multiple locations for integration of WG in the system.

Probabilistic Assessment of Available Transfer Capability Incorporating Load and Wind Power Uncertainties

“…Also, the table lists the most severe contingency case related to each scenario, which is important for the system operator to take into account for any line outages that might occur for any transaction. For example, the most severe lines for 100% of the original system load for T1 are lines (1-3), (2-6), and (22)(23)(24). This implies that the evaluated ATC value in the proposed method addresses not only one severe contingency, but numerous serious ones correlated with the invigilated scenarios, making it more conservative for a variety of potentially uncertain circumstances.…”

“…ATC is calculated for online application using fast calculation technique in [23]. In [24], an average transmission congestion distribution factor method is proposed to determine the optimal location of a wind farm for ATC enhancement. ATC evaluation considering the uncertainty of wind energy based on relative distance measure arithmetic approach is presented in [25].…”
