MI-Convex Approximation for the Optimal Siting and Sizing of PVs and D-STATCOMs in Distribution Networks to Minimize Investment and Operating Costs

Electricity
The optimal integration of photovoltaic (PV) systems and distribution static synchronous compensators (D-STATCOMs) in electrical distribution networks is important to reduce their operating costs, improve their voltage profiles, and enhance their power ...

Co‐Optimisation of Battery Energy Storage Systems for Voltage Regulation and Reverse Power Flow Control in PV‐Enriched Low Voltage Distribution Network

IET Smart Energy Systems, EarlyView.
A hybrid GA–PSO framework determines the optimal placement and sizing of distributed battery energy storage systems in a PV‐enriched low voltage feeder, whereas dynamic consensus control (DCC) coordinates their operation. The integrated approach mitigates voltage rise and reverse power flow and promotes balanced utilisation of multiple storage units ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Volume Quantization with Flexible Singularities for Hexahedral Meshing

Computer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Embedding Optimization of Layouts via Distortion Minimization

Computer Graphics Forum, EarlyView.
Abstract Given an embedding of a layout in the surface of a target mesh, we consider the problem of optimizing the embedding geometrically. Layout embeddings partition the surface into multiple disk‐like patches, making them particularly useful for parametrization and remeshing tasks, such as quad‐remeshing, since these problems can then be solved on ...

A hybrid robust‐stochastic optimization approach for green hydrogen production planning under wind power forecast uncertainty

International Transactions in Operational Research, EarlyView.
Abstract This work aims at minimizing the energy purchase costs related to the operation of a green hydrogen production plant connected both to an intermittent, uncertain renewable energy source and to the power grid. We focus on scenarios where, for economic or environmental reasons, the plant must primarily meet hydrogen demand using electricity from

maxRgain—An R Package for Maximising Genetic Gains in Polyclonal Selection

Plant Breeding, EarlyView.
ABSTRACT Polyclonal selection, which was developed in the context of ancient grapevine varieties, uses intravarietal variability to improve the resilience and sustainability of viticulture. Based on quantitative genetics and linear mixed models, this approach predicts genotypic effects to select a group of clones that, as a whole, satisfy target ...

A stochastic mixed-integer convex programming model for long-term distribution system expansion planning considering greenhouse gas emission mitigation

International Journal of Electrical Power & Energy Systems, 2019
This paper proposes a multistage convex distribution system planning model to find the best reinforcement plan over a specified horizon. This strategy determines planning actions such as reinforcement of existing substations, conductor replacement of ...
