Model predictive control of vehicle charging stations in grid-connected microgrids: An implementation study

The transition to renewable energy sources, particularly sources like wind and solar induces a dependency on weather in the supply side of electrical grids. At the same time, the move to electric mobility with uncontrolled charging induces extra peak loads on these grids. These developments can cause grid congestion or an imbalance between the...

EV Smart Charging in Distribution Grids - Experimental evaluation using Hardware in the Loop Setup

The rising demand for electric vehicles (EVs) in the face of limited grid capacity encourages the development and implementation of smart charging (SC) algorithms. Experimental validation plays a pivotal role in advancing this field. This article formulates a hierarchical mixed integer programming EV SC algorithm designed for low voltage (LV)...

Interplay between LV Grids and EVs’ Charging Flexibility: A Smart Charging Approach

The electrification of all sectors is essential to achieve carbon neutrality by 2050. In terms of mobility, many nations around the globe envisage a zero-emission fleet resulting in a massive deployment of Electric Vehicles (EV). Nevertheless, this goes hand-in-hand with some challenges related to congestion and voltage problems in power grids...

Smart contracts in energy systems: A systematic review of fundamental approaches and implementations

Given the ongoing transition towards a more decentralised and adaptive energy system, the potential of blockchain-enabled smart contracts for the energy sector is being increasingly recognised. Due to their self-executing, customisable and tamper-proof nature, they are seen as a key technology for enabling the transition to a more efficient,...

Real-time building smart charging system based on PV forecast and Li-Ion battery degradation

This paper proposes a two-stage smart charging algorithm for future buildings equipped with an electric vehicle, battery energy storage, solar panels, and a heat pump. The first stage is a non-linear programming model that optimizes the charging of electric vehicles and battery energy storage based on a prediction of photovoltaïc (PV) power,...

Optimisation based design of an integrated energy system in the Netherlands: A case study at Picnic

As the share of solar and wind in the energy mix increases, the inherent intermittency of these energy sources pose a great challenge for the Dutch power grid. The occurrence of problems with congestion and balancing power supply and demand are becoming more common. Companies in the Netherlands show potential to implement means for smart use of...

Smarter Charging: Modeling optimal EV charging in solar parking lots for reducing peak demand, considering uncertainty in solar power forecasting and EV energy demand

Smart charging offers the potential for electric vehicles to use renewable energy more efficiently, lowering costs and improving the stability of the electricity grid. Many computer models have been developed to simulate the behavior of smart charging. Yet these models often assume that future information is known perfectly, including when...

Optimisation of smart-and Vehicle-to-Grid charging strategies in distribution networks: based on charging behaviour analysis

Currently in the energy system of the Netherlands, lower level consumer demand flexibility is rather obsolete due to sufficient capacity limits of the distribution network and supply of capacity mechanisms by large industrial actors. However, in the upcoming 10- 20 years, the power system is in transition to become decentralised with a higher...

Exploring the role of battery electric and fuel cell electric vehicles in a sustainable smart city

Battery electric and fuel cell electric vehicles have the potential to cover the shortage in renewable power generation by engaging in vehicle-to-grid. However, the vehicle-to-grid service cannot completely make up for the intermittent nature of renewables. Deterministic models were used to compute the extent to which the vehicles can engage in...
