AbstractThe transformation of the energy system towards volatile renewable
generation, increases the need to manage decentralized flexibilities more
efficiently. For this, precise forecasting of uncontrollable electrical load is
key. Although there is an abundance of studies presenting innovative individual
methods for load forecasting, comprehensive comparisons of popular methods are
hard to come... hiện toàn bộ
Abstract The analysis of electrical load signatures is an enabling technology
for many applications, such as ambient assisted living or energy-saving
recommendations. Through the digitalization of electricity metering
infrastructure, meter reading intervals are gradually becoming more frequent
than the traditional once-per-year reporting. In fact, across smart meter
generations, samples were initi... hiện toàn bộ

Abstract The increasing penetration of residential photovoltaics (PV) comes with
numerous challenges for distribution system operators. Technical difficulties
arise when an excess of PV energy is injected into the grid, causing voltage
rise or overloading of the lines. Economic challenges appear because PV owners
and consumers are not participating equally in the grid costs. Indeed, PV owners
bene... hiện toàn bộ

AbstractA growing demand in sustainable energy harvested from renewable
resources, such as wind or solar power, leads to new challenges in the
electricity grid, which in future is also referred to as the smart grid. This
also reflects in a more decentralized and diverse energy market. In such a
market, prices do not only depend on production and demand, but also the source
of energy production inf... hiện toàn bộ

AbstractUnlocking and managing flexibility is an important contribution to the
integration of renewable energy and an efficient and resilient operation of the
power system. In this paper, we discuss how the potential of a fleet of
battery-electric transportation vehicles can be used to provide frequency
containment reserve. To this end, we first examine the use case in detail and
then present the ... hiện toàn bộ

AbstractDigital twin technologies have become popular in wind energy for
monitoring and what-if scenario investigation. However, developing a digital
representation of the wind is challenging, especially due to the digital twin
platform constraints. Game engines might be possible to solve this issue,
especially since game engines have been used for product design, testing,
prototyping, and also di... hiện toàn bộ
