Convex Model for Estimation of Single-Phase Photovoltaic Impact on Existing Voltage Unbalance in Distribution Networks
Verner Püvi,Matti Lehtonen +1 more
TL;DR: A Monte Carlo simulation augmented with convex mixed-integer quadratic programming to estimate voltage unbalance and maximum photovoltaic penetration revealed substantial unbalance attenuation with optimal phase selection and increased potential of local generation hosting capacity in case of higher background unbalance.
Journal ArticleDOI
Feasibility study of energy storage options for photovoltaic electricity generation in detached houses in Nordic climates
TL;DR: In this paper , the authors evaluate the cost-effectiveness of utilizing energy storages to enhance residential photovoltaic electricity generation in the Nordic climate, and they find that the use of energy storage is the most financially feasible storage option with costs relatively close to stand-alone solar PV systems.
Journal ArticleDOI
Cost-Optimal Renovation Solutions for Detached Rural Houses in Severe Cold Regions of China
TL;DR: In this article , the authors presented the cost-optimal envelope renovation solutions with the minimized lifecycle cost (LCC) during a 20-year discount period and CO2 emissions of annual delivered energy consumptions.
Journal ArticleDOI
Hosting capacity in distribution grids: A review of definitions, performance indices, determination methodologies, and enhancement techniques
TL;DR: In this paper , an extensive review of all the hosting capacity (HC) terms, references, limiting constraints of the studied networks, geographical segregation, and their determination methodologies is presented, and the factors defining the HCs of various networks and the architectures employed to increase them are also explained briefly in the conducted review study.
