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

    Abstract The occurrence of distortion and over voltage at the Point of Common Coupling (PCC) of Renewable Distributed Generation (RDG) limits its penetration levels to the power system and the RDG integration is expected to play a crucial role in power system transformation. For its penetrations to be sustained without disconnection from the system, there must be a solution to the voltage rise, distortion, unbalanced current and grid reactive power control strategy at PCC. It is an IEEE-1547 requirement that RDG integration to the power system should be regulated at PCC to avoid disconnection from the… More >
