Nearly half the electricity produced in the Netherlands is now renewable
In 2023, 48 percent of electricity was generated from renewable sources such as solar, wind and water. Between May and July, over half of the electricity generated in the Netherlands was from renewable sources, and that share reached as high as 57 percent in July. Production from renewable sources increased by 21 percent in 2023 compared with the previous year. The share of electricity generated from fossil fuels fell, and the Netherlands exported more electricity to neighbouring countries than…

Co-Optimizing Distributed Energy Resources in Linear Complexity under Net Energy Metering
The co-optimization of behind-the-meter distributed energy resources is considered for prosumers under the net energy metering tariff. The distributed energy resources considered include renewable generations, flexible demands, and battery energy storage systems. An energy management system co-optimizes the consumptions and battery storage based on locally available stochastic renewables by solving a stochastic dynamic program that maximizes the expected operation surplus.

Renewable levelized cost of energy available for export: An indicator for exploring global renewable energy trade potential
Renewable energy resources are widely available, yet they are unevenly distributed globally. In a renewable future, countries lacking high-quality renewable resources may choose to import energy from other countries. To assess the resource-dependent and techno-economic basis for global renewable energy trade and identify potential importers and exporters, this study introduces two new metrics: Renewable Levelized Cost of Energy available for Export (RLCOE_Ex) and Potential Energy Export Volume …

Just 1,200 square kilometers of land could fulfill Australia's solar and wind energy needs
As Australia's rapid renewable energy rollout continues, so too does debate over land use. Nationals Leader David Littleproud, for example, claimed regional areas had reached "saturation point" and cannot cope with more wind and solar farms and transmission lines.

How China Became the World’s Leader on Renewable Energy
China has achieved stunning growth in its installed renewable capacity over the last two decades, far outpacing the rest of the world. But to end its continued dependence on fossil fuels, it must now move ahead with planned reforms to its national electricity system.

HUGO -- Highlighting Unseen Grid Options: Combining Deep Reinforcement Learning with a Heuristic Target Topology Approach
With the growth of Renewable Energy (RE) generation, the operation of power grids has become increasingly complex. One solution is automated grid operation, where Deep Reinforcement Learning (DRL) has repeatedly shown significant potential in Learning to Run a Power Network (L2RPN) challenges. However, only individual actions at the substation level have been subjected to topology optimization by most existing DRL algorithms. In contrast, we propose a more holistic approach in this paper by pro…

Establishing best practices for modeling long duration energy storage in deeply decarbonized energy systems
Long duration energy storage (LDES) may become a critical technology for the decarbonization of the power sector, as current commercially available Li-ion battery storage technologies cannot cost-effectively shift energy to address multi-day or seasonal variability in demand and renewable energy availability. LDES is difficult to model in existing energy system planning models (such as electricity system capacity expansion models), as it is much more dependent on an accurate representation of c…

On Optimal Management of Energy Storage Systems in Renewable Energy Communities
Renewable energy communities are legal entities involving the association of citizens, organizations and local businesses aimed at contributing to the green energy transition and providing social, environmental and economic benefits to their members. This goal is pursued through the cooperative efforts of the community actors and by increasing the local energy self-consumption. In this paper, the optimal energy community operation in the presence of energy storage units is addressed. By exploit…

Joint Chance-constrained Game for Coordinating Renewable Microgrids with Service Delivery Risk: A Bayesian Optimization Approach
Microgrids incorporate distributed energy resources (DERs) and flexible loads, which can provide energy and reserve services for the main grid. However, due to uncertain renewable generations such as solar power, microgrids might under-deliver reserve services and breach day-ahead contracts in real-time. If multiple microgrids breach their reserve contracts simultaneously, this could lead to a severe grid contingency. This paper designs a distributionally robust joint chance-constrained (DRJCC)…

Control Policy Correction Framework for Reinforcement Learning-based Energy Arbitrage Strategies
A continuous rise in the penetration of renewable energy sources, along with the use of the single imbalance pricing, provides a new opportunity for balance responsible parties to reduce their cost through energy arbitrage in the imbalance settlement mechanism. Model-free reinforcement learning (RL) methods are an appropriate choice for solving the energy arbitrage problem due to their outstanding performance in solving complex stochastic sequential problems. However, RL is rarely deployed in r…

Nonlinear Voltage Regulation of an Auxiliary Energy Storage of a Multiport Interconnection
In this article, we propose a nonlinear voltage control to ensure power exchange in a multiport interconnected system, which consists of a bidirectional DC-DC converter and generating-storing devices. The converter topology under consideration is two-stage, composed of an interconnection of a buck with a boost converter. The motivation for this work is the explosive increase in the use of DC-DC converters due to the massification of renewable energies, electric vehicles powertrains, and energy …
