Transmission Expansion Planning Considering a High Share of Wind Power to Maximize Available Transfer Capability

To have an effective transmission network and support free trading, the open non-discriminatory access to services for all market participants under conditions is of significant concern. this end, a sufficient value available transfer capability (ATC) required, which can significantly affect electricity efficiency. This paper constructs methodology reinforcing existing considering wind power investment enhance ATC. In regard, bi-level structure adopted whose upper level joint expansion planning (TEP) subject technical grid limitations. After solving level, security-constrained economic dispatch (SC-ED) formulated acquire optimal generation scheduling. Then, lower designed calculate solve problem, SC-ED first replaced by its primal dual feasibility constraints strong duality equality. these are added level. The also corresponding constraints. Consequently, bilinear single-level optimization problem extracted, further solved employing Konno’s cutting plane algorithm. experimental results on IEEE 24-bus RTS show proposed method’s effectiveness. It indicated that ATC be improved 27.2 % using model at expense more cost resulting in less load shedding curtailment.
