Sketch-Based Optimisation for Distribution Grid Expansion Planning: User-driven research to accelerate distribution grid expansion planning at Alliander

Distribution Network Operators (DNOs) are confronted with a significant challenge to expand the capacity of the electricity distribution grid to facilitate the energy transition. Grid expansion planning for the distribution grid is a complex problem with many constraints and objectives. Earlier research has focused on metaheuristics such as...

Battery Storage System as Power Unbalance Redistributor in Distribution Grids Based on Three Legs Four Wire Voltage Source Converter

This article discusses the application of battery energy storage systems (BESSs) as power redistributors in three-phase distribution grids as an add-on functionality to typical BESS applications, such as congestion management and energy arbitrage. Combining those ancillary services into a single power unit is not yet performed in practice but...

Distributed Transactive Framework for Congestion Management of Multiple-Microgrid Distribution Systems

The privatization of distribution systems has resulted in the development of multiple-microgrid (multiple-MG) systems where each microgrid independently operates its local resources. Moreover, the high integration of independent distributed energy sources could lead to operational issues such as grid congestion in future distribution systems....

Conditions for Profitability & Grid Effects of PV-Electrolysis

In this graduation research conditions affecting the profitability as well as the grid effects of a PV-Electrolysis system have been studied using the site of PV park Oosterwolde as a case study. During the study a wide variety scenarios have been created from a set of influential parameters on the PV-Electrolysis business case, which have...

Priorização dinâmica e espacial de alimentadores para o corte seletivo de carga em redes de distribuição

To keep the balance between energy consumption and supply in the short-term, proper planning is needed, which is subject to contingencies that interfere with its dynamics. Major events in the Brazilian Interconnected System can lead to variations in frequency and voltage, and real-time operation centers must act quickly and effectively to avoid...

Direct Current Power Flow: Computational methods and low voltage applications

Technical developments in generation and demand of energy will motivate significant change in the electric power grid, both on the transmission and the distribution level. A major innovation would be the successful transformation of the current passive power grid towards an active and ICT-based smart grid. Among the technical efforts that will...

Scalable model districts for geographic load forecasting in the distribution grid

The electrical peak demand in the Netherlands is likely to increase due to renewable energy technologies, and create a higher load demand for distribution transformers. Two technologies that increase the peak demand are solar-PV and heat pumps, for which the deployment on the distribution grid differs largely between geographical areas. In this...

The Power of Electric Vehicles - Exploring the Value of Flexible Electricity Demand in a Multi-actor Context

Electric vehicles (EVs) have the potential to play a crucial role in clean and intelligent power systems. The key to this potential lies in the flexibility that EVs provide by the ability to shift their electricity demand in time. This flexibility can be used to facilitate the integration of renewable energy sources by adjusting EV demand to the...
