Multiobjective optimal generation dispatch based on probability security criteria
TLDR
In this article, an efficient algorithm is proposed to obtain the optimal power flow in power system operation and planning phases by multiobjective optimization, which makes it possible to treat the optimal dispatch problems with multiple performance indices and to include tradeoff relations between selected indices.Abstract:
An efficient algorithm is proposed to obtain the optimal power flow in power system operation and planning phases by multiobjective optimization. The algorithm makes it possible to treat the optimal dispatch problems with multiple performance indices and to include tradeoff relations between selected indices. The effect of uncertain factors pertaining to power systems can also be taken into account. The effectiveness of the approach is illustrated with numerical examples of the IEEE 30-node, 6-generator system. >read more
