Coordinated allocation of distributed generation, soft open points and energy storage systems in unbalanced distribution networks considering flexibility deficiency risk

Alexandria Engineering Journal
Optimizing the location and capacity of flexible resources is critical. The increase in the permeability of distributed generation (DG) causes the net load to drastically fluctuate, which sharply increases flexibility demand for the distribution network.

A solving tool for fuzzy quadratic optimal control problems [PDF]

In this paper we propose an iterative method to solve an optimal control problem, with fuzzy target and constraints. The algorithm is developed in such a way as to satisfy the target function and the constraints.

Immunizing Conic Quadratic Optimization Problems Against Implementation Errors [PDF]

We show that the robust counterpart of a convex quadratic constraint with ellipsoidal implementation error is equivalent to a system of conic quadratic constraints.

Quadratic programming problems. [PDF]

, 2011
In this paper we consider applications of quadratic programming to solving some problems. First of all we define a quadratic programming problem as an optimization problem with a quadratic objective function and some constraints. We present two important
