A QCQP Approach for OPF in Multiphase Radial Networks with Wye and Delta Connections: Preprint
Abstract
This paper examines the AC Optimal Power Flow (OPF) problem for multiphase distribution networks featuring renewable energy resources (RESs). We start by outlining a power flow model for radial multiphase systems that accommodates wyeconnected and deltaconnected RESs and noncontrollable energy assets. We then formalize an AC OPF problem that accounts for both types of connections. Similar to various AC OPF renditions, the resultant problem is a non convex quadraticallyconstrained quadratic program. However, the socalled Feasible Point PursuitSuccessive Convex Approximation algorithm is leveraged to obtain a feasible and yet locallyoptimal solution. The merits of the proposed solution approach are demonstrated using two unbalanced multiphase distribution feeders with both wye and delta connections.

This paper focuses on multiphase radial distribution networks with mixed wye and delta connections, and proposes a semidefinite relaxation of the AC optimal power flow (OPF) problem. Two multiphase powerflow models are developed to facilitate the integration of deltaconnected generation units/loads in the OPF problem. The first model extends traditional branch flow models  and it is referred to as extended branch flow model (EBFM). The second model leverages a linear relationship between perphase power injections and delta connections, which holds under a balanced voltage approximation (BVA). Based on these models, pertinent OPF problems are formulated and relaxed to semidefinitemore »

Convex Relaxation of OPF in Multiphase Radial Networks with Wye and Delta Connections
This panel presentation focuses on multiphase radial distribution networks with wye and delta connections, and proposes a semidefinite relaxation of the AC optimal power flow (OPF) problem. Two multiphase power flow models are developed to facilitate the integration of deltaconnected loads or generation resources in the OPF problem. The first model is referred to as the extended branch flow model (EBFM). The second model leverages a linear relationship between phasetoground power injections and delta connections that holds under a balanced voltage approximation (BVA). Based on these models, pertinent OPF problems are formulated and relaxed to semidefinite programs (SDPs). Numerical studiesmore » 
Linear PowerFlow Models in Multiphase Distribution Networks: Preprint
This paper considers multiphase unbalanced distribution systems and develops approximate powerflow models where busvoltages, linecurrents, and powers at the point of common coupling are linearly related to the nodal net power injections. The linearization approach is grounded on a fixedpoint interpretation of the AC powerflow equations, and it is applicable to distribution systems featuring (i) wye connections; (ii) ungrounded delta connections; (iii) a combination of wyeconnected and deltaconnected sources/loads; and, (iv) a combination of linetoline and linetogroundedneutral devices at the secondary of distribution transformers. The proposed linear models can facilitate the development of computationallyaffordable optimization and control applications  frommore » 
Object detection approach using generative sparse, hierarchical networks with topdown and lateral connections for combining texture/color detection and shape/contour detection
An approach to detecting objects in an image dataset may combine texture/color detection, shape/contour detection, and/or motion detection using sparse, generative, hierarchical models with lateral and topdown connections. A first independent representation of objects in an image dataset may be produced using a color/texture detection algorithm. A second independent representation of objects in the image dataset may be produced using a shape/contour detection algorithm. A third independent representation of objects in the image dataset may be produced using a motion detection algorithm. The first, second, and third independent representations may then be combined into a single coherent output using amore »
