Abstract China Energy’s National Institute of Clean-and-Low-Carbon Energy (NICE) is developing a Power Plant Smart Management (PPSM) platform that employs digital-twin technology to undertake techno-economic modelling analysis on existing coal-fired power-plant units and explore cost-effective solutions improve those plant units’ thermal efficiencies operating performance. This paper presents case study PPSM 320-MWe unit, demonstrating how the was employed analyse optimization solutions....

Due to the short-term large-scale access of renewable energy and residential electric vehicles in communities, voltage limit distribution network will be exceeded, quality power supply seriously reduced. Therefore, this paper introduces mobile storage system (MESS), which effectively solves problem overvoltage caused by large number distributed sources household network. This proposes an optimal scheduling model for based on system. First, space-time transfer is established, cost MESS income...

The power supply and distribution network of prosumer group is equipped with contact switch section switch. After feeder fault occurs, the topological structure can be adjusted by changing state each in system, so as to realize reconstruction after fault, restore free area. optimal configuration different types switchgear appropriate position reduce time location isolation, further reconfiguration which greatly improves reliability for group. This paper introduces a series Boolean...

A considerable market share of electric vehicles (EVs) is expected in the near future, which leads to a transformation from gas stations EV charging infrastructure for automobiles. will be integrated with power grid replace fuel consumption at same mobile needs. In order evaluate impact on distribution networks and controllability load, temporal spatial calculated by establishing mapping relation between facilities. Firstly, arrival parking period quantified applying queuing theory defining...

Abstract With the rapid development of renewable energy, distributed PV access to distribution grid has become a common form. However, network (DN) may cause voltage overrun problems, which brings challenges stability and reliability DN. In order reasonably assess impact connection, paper proposes probabilistic trend calculation based on quasi-Monte Carlo mode method obtain node probability under premise considering stochastic nature power generation load fluctuation, combines with utility...

This paper proposes a novel method of locating the disturbance source forced power oscillation based on equivalent electrical distance. Firstly, actual grid nodes are mapped onto complex plane basis distance theory. Secondly, PMU monitoring selected according to defined index coupling degree generator and load. Lastly, is effectively located by resolving optimization problem Geiger theory seismology half-plane method. proposed can be implemented acquiring analyzing waveforms frequency...

With the large-scale access of distributed resources to distribution network operation, there are more and prosumers on user side. It forms basis load prediction demand-side management identify different power consumption patterns establish a typical characteristic database according data prosumers. Therefore, method build prosumer based deep convolutional autoencoder is proposed. First, was used extract features collected reduce dimension. Then, density weight canopy algorithm precluster...

Abstract In the context of Smart Grid 2.0, intelligent power terminals are an important part smart grid, but their weak security protection can easily become main target and springboard for criminals to attack grid. Therefore, ensuring is key protect grids. this context, paper through analysis terminal threats, proposes a three-layer framework including “physical layer”, “operating system layer” “communication thus proposed strategy devices, which aims comprehensively improve comprehensively.

Due to the differences of subway train running interval in time scale and space scale, load power supply network is not evenly distributed space, which results unbalanced lines main transformers, reducing reliability network. By analyzing structure network, this paper firstly establishes station model based on timetable then model, a multi-objective optimization was constructed with objective function minimizing weighted loss, voltage drop unbalance, reconfiguration realized by switching...
