Deterministic approach for solving multi-objective non-smooth Environmental and Economic dispatch problem
(2019-01-01)
The Environmental and Economic Dispatch Problem with Valve-Point loading effect representation (EEDP-VP) is a multi-objective, nonconvex and non-differentiable optimization problem. Due to these difficulties, it has been ...
A primal-dual interior/exterior point method, with combined directions and quadratic test in reactive optimal power flow problems
(2017-01-01)
In this paper, we propose a primal-dual interior/ exterior point method that uses the modified logarithmic barrier function together with a quadratic test strategy and new search direction procedures for solving the reactive ...
Solving network-constrained nonsmooth economic dispatch problems through a gradient-based approach
(2019-12-01)
The Network-Constrained Nonsmooth Economic Dispatch (NCNS-ED) is formulated as a nonsmooth, nonconvex and multimodal optimization problem. Nonsmoothness is generally associated with valve-point loading effects in the cost ...
