Heuristic remedial actions in the reliability assessment of high voltage direct current networks

<p>Planning of high voltage direct current (HVDC) grids requires inclusion reliability assessment alternatives under study. This paper proposes a methodology to evaluate the adequacy source converter/VSC-HVDC networks. The analyses performance system using N-1 and N-2 contingencies in order detect weaknesses DC network evaluates two types remedial actions keep entire acceptable operating limits. are applied when violation these limits on occurs; those include topology changes adjustments power settings VSC converter stations. CIGRE B4 grid test is used for evaluating reliability/adequacy by means proposed this paper. effective all contingencies; then, numerical results as expected. work useful planning operation based VSC-HVDC technology.</p>
