The rapid addition of distributed energy resources to the utility grid represents an integration challenge for DNOs. One-off integration of small scale resources is impractical, and so standards-based approaches offer significant cost and efficiency improvements. This presentation will include a case study on the integration of EV charging infrastructure, which has been the fastest growing category of the OpenADR information exchange model.
This talk will discuss how Local Energy Communities can become more green and self-sufficient by participating in a novel concept called Layered Energy System (LES). The talk will outline the core principles and benefits of LES not only for communities, but also for the energy grid as a whole. i.LECO has developed a prosumer portal that is the single interaction point of community residents with the LES concept – and that portal will be demonstrated in the talk. The LES concept has already been deployed to two local communities in the Netherlands and the talk will focus on a pilot in the Woerden district.
Investments for energy-infrastructure expansion are not easy to determine due to the deep uncertainties related to the energy transition and the growing need for system flexibility. These deep uncertainties call for a robust adaptive investment plan for an integrated energy-infrastructure. In the Gridmaster initiative a tool is developed to create such robust investment plans.
Gridmaster is a co-operation between Siemens, TenneT, Stedin, Port of Rotterdam, TU Delft, Gasunie and the province of South Holland.
“The grid edge is the place where the biggest part of the energy transition takes place”. A sentence you here a lot in the utility world. This statement was for Siemens and Alliander the motivation to dive deeper in the grid edge. Technologies such as PV, EV and heat pumps are becoming rapidly common practice in the low-voltage distribution grid. All of these technologies have one thing in common: they increase the load on the grid. The goal for the joint project was to develop a method to forecast the load on the low-voltage section of the grid, without the use of smart meter data. This in order to have a more accurate load-forecasting for residential areas. In addition it has also been a case in which Siemens and Alliander were able to test and develop new hardware together.
For this project, Alliander selected a residential area where existing houses have completely been overhauled to achieve zero-energy homes. This means that those overhauled homes are being equipped with the afore mentioned technologies. In order to have a better view on the load characteristics, Siemens installed additional measuring equipment in the low-voltages street cabinets and connected them to the higher level cloud system. Together with Omnetric, Siemens developed a cloud based system to have more accurate load forecasting in the low voltage section of the grid, without having the need of smart meter data.
Vehicle-to-grid (V2G): The aim is pilot test the possibilities/capabilities of delivery of FCR by parked EVs – comparing between unidirectional and bi-directional (V2G) charging poles. By the time of FLEXCON the initiative we should be able to present final outcomes. This is an initiative performed by Elia in collaboration with NewMotion, EVConsult & Enervalis with the backing of Flemish government funding. For this session the idea is to have a co-presentation between Elia and Enervalis.
Flexibility is a key enabler of extensive penetration of renewable power generation.
Ranging from various forms of demand response to fuel switching, a wide range of flexibility solutions are being developed and trialed by energy companies, aggregators, communities, and end-users globally.
Inspired by a recent Guidehouse study completed for TKI Urban Energy on the lessons learned from flexibility pilots in the Netherlands, Ben Grunfeld will reflect on flexibility programs in the Netherlands, the US, and the UK. He will also share insights on developing and operationalizing flexibility programs in a commercially viable way for various stakeholders across the flexibility value chain.
Arjan will explore (open) standards and protocols for unlocking energy flexibility for the in-home and building domain
The electricity system is slowly but surely coming under pressure due to the energy transition. The strong growth of sustainable and decentralized generation entails intermittent electricity production, fluctuating due to the weather. As a result, a balance is increasingly being sought between supply and demand. We strive for unlocking flexibility from the potential flexible devices in-home (amongst others) as a measure to cope with this challenge.
To be able to control a device to unlock flexibility, connectivity, a communication channel, is required between the device and the external party that asks for this flexibility. This connectivity is a precondition for energy flexibility. ElaadNL has performed a study which focuses on the technical (im)possibilities for unlocking the flexibility of various potentially flexible devices. This study has provided insight in the ways in which flexibility can be unlocked from different flexible devices. These insights are shared at Flexcon2020.
Frauke and Bert will close the conference and summarize the highlights.
