Peak-Load Management of Distribution Network Using Conservation Voltage Reduction and Dynamic Thermal Rating

Sustainability, Год журнала: 2022, Номер 14(18), С. 11569 - 11569

Опубликована: Сен. 15, 2022

The peak-load management of a distribution network (DN) has gained attention by increasing the electric power consumption on demand side. By developing smart-grid infrastructures, effective utilization DN’s components and proper DN would create valuable solution for operators. Hence, in this paper, framework is proposed which real-time rating voltage-dependent features loads help operator handle peak times successfully. In addition to individual advantages efficient operation DN, more practical results are obtained combining conservation voltage reduction (CVR) dynamic thermal (DTR) lines transformers. Based results, compared implementation CVR, cost-saving level increased significantly during events using simultaneous DTR CVR. Furthermore, discussion presented about current problems feeders supplying constant-power CVR utilization, resolved components.

Energy flexibility of commercial buildings for demand response applications in Australia

Energy and Buildings, Год журнала: 2023, Номер 300, С. 113533 - 113533

Demand response (DR) is widely recognized as an important mechanism in the Australian electricity market, though large-scale uptake commercial buildings yet to occur, part due difficulty of characterising resource. This paper describes a bottom-up physics-based approach characterise DR potential three types (schools, offices, and data centres) under global set-point temperature offset strategy. Representative models are calibrated with energy meter parametric analysis used assess sensitivity different building, operating system parameters. Parametric equations provided for relative potentials functions time day. School were found have highest (∼40 - 45%) ambient temperatures over 30°C, followed by centres (∼20 30%) offices (∼20%). Location has strongest influence school office equipment intensity centres. The Australia-wide combined school, estimated be between 551 647 MW. Office aggregate at 1.5 1.7 times that 9 11

Analysis of Peak Demand Reduction and Energy Saving in a Mixed-Use Community through Urban Building Energy Modeling

Energies, Год журнала: 2024, Номер 17(5), С. 1214 - 1214

Опубликована: Март 3, 2024

Energy saving in buildings is essential as buildings’ operational energy use constitutes 30% of global consumption. Urban building modeling (UBEM) effectively understands urban This paper applied UBEM to assess the potential peak demand reduction and a mixed-use community, using 955 residential buildings, 35 office 7 hotels Shenzhen, China, case study. The type period were collected based on GIS dataset. Then, baseline models generated by tool—AutoBPS. Five scenarios analyzed: retrofit-window, retrofit-air conditioner (AC), retrofit-lighting, rooftop photovoltaic (PV), response. five replaced windows, enhanced AC, upgraded lighting, covered 60% roof area with PV, had temperature reset from 17:00 23:00, respectively. results show that retrofit-windows most effective scenario for reducing at 19.09%, PV reduces intensity (EUI) best 29.96%. Demand response recommended when further investment not desired. Retrofit-lighting suggested its low-cost, low-risk investment, payback (PBP) exceeding 4.54 years. When abundant, are public while buildings. research might provide practical insights into policy formulation.
