Periodic Reporting for period 1 - HYPERRIDE (Hybrid Provision of Energy based on Reliability and Resiliency by Integration of Dc Equipment)
Período documentado: 2020-10-01 hasta 2022-03-31
The HYPERRIDE project contributes to the field implementation of Direct Current (DC) and hybrid Alternating Current and Direct Current (ACDC) grids. Starting with the definition of the most relevant fields of application for DC grids (local microgrids, grid enforcement to overcome congestions, coupling of Alternating Current (AC) grid sections, etc.), the enabling technologies will be specified in detail on different levels.
From the system perspective, grid planning and operation guidelines are developed. To optimize investments for the use case-dependent use of assets available sizing tools are adapted for the field of DC grids. DC circuit breakers are key technologies for grid protection needed to overcome the main concerns related to these infrastructures. Therefore, HYPERRIDE will raise the Technology Readiness Level (TRL) of the most promising approaches currently available with the main focus on Medium Voltage Direct Current (MVDC) breakers. To enable grid automation DC sensors are developed further to provide field-ready devices to create data for optimal grid automation. Automation algorithms will be created, validated in a test platform and transferred towards demonstration. This also involves concepts and solutions for cyber security and fault detection. In the case of grid faults, necessary solutions are developed to prevent cascading effects. For fault prevention databases are created to trigger preventive measures.
With demonstrations in three countries (Aachen/Germany, Lausanne/Switzerland, Terni/Italy) the project will showcase relevant and above-mentioned enabling technologies within a wide range of use cases. The benefits of the solutions will be evaluated, especially the integration potential of renewables and electric vehicle charging with respect to conventional AC grids. Finally, business models are created for the products, services and applications in HYPERRIDE. Consequently, HYPERRIDE will actively identify and provide solutions to overcome barriers for a successful roll-out of new infrastructure concepts throughout Europe.

Dealing with the demonstration of hybrid ACDC grids, which were seen as one potential technology to overcome future bottlenecks of power grids (utility, industry, infrastructure) in energy transition and to enable energy communities, aims to
• lift specific required key technologies and system solutions to higher TRLs (target area 5-8),
• collect essential operational experience with these technologies,
• highlight benefits and cost-effective solutions for relevant use cases,
• trigger manufacturers to step in recently with product developments and standardization work, and
• foster on a mid-term perspective further investment in the field for a successful roll-out over Europe.
Therefore, knowledge transfer across European (via BRIDGE and other channels) and international pilot projects and initiatives is crucial to lift synergies and therefore accelerate the technology development and standardization process and include relevant stakeholders’ interests.
