Summary
Currently the global energy system is mostly based on fossil fuels,
which is unsustainable over the long-term due to various reasons such as
negative climate change impacts, negative health impacts, depletion of fossil
fuel reserves, challenge to preserve ecosystems and resources for future
generations. Economic, environmental, and security concerns associated with
conventional fuel supplies have strengthened support for clean energy
technologies among governments and the private sector on a global scale. Renewable
energy is an alternative to the traditional energy that relies on fossil fuels,
and it tends to be much less harmful to the environment. Renewable sources,
such as wind and solar, can pose difficulties because their output can vary
according to seasonal and daily patterns and be uncertain due to changes in the
weather. Yet, questions about how to effectively integrate large amounts of
variable renewable energy generation persist. Without effective integration
methods, increasing renewable penetration, along with transmission and capacity
expansion can present challenges for an energy system’s stability and
reliability. The aim of the Special Issue is, as the title explains, to
understand how higher penetrations of variable renewable energy generation will
impact the energy systems, and the scope includes:
System operation: Strategic renewable energy
curtailment, Joint system operation, Sub-hourly scheduling and dispatch
Market Design: Energy market design, Ancillary service liquidity, Joint market
operation
Generation forecasting: Time series,
Machine learning algorithms
Increasing flexibility: Flexible
generation, Demand response and demand side management, Flexible transmission
Storage: Thermal storage, Battery, Power-to-X, Pumped hydro storage
Business models: Aggregators, Peer-to-peer
electricity trading, Energy-as-a-service, Community-ownership models,
Pay-as-you-go-models
Keywords
Renewable energy, energy integration, energy storage, renewable energy forecasting, energy market, Business models
