RESOLVD is H2020 research and innovation action (LCE-01-2016-2017. Ref. 773715, https://resolvd.eu) coordinated by the Universitat de Girona and participated by other six partners: Joanneum Research (Research center, Austria), Smart Innovation Norway (Research center, Norway), Universitat PolitÃ¨cnica de Catalunya (Univ, Spain), Comsensus (SME, Slovenia), Intracom Telecom (Industry, Greece) and Estabanell Energia (SME/DSO, Spain) that aims to contribute to setting the next generation of competitive technologies and services for smart grids.
The overall objective of RESOLVD is to improve efficiency and the hosting capacity of distribution networks in a context of highly distributed renewable generation by introducing energy flexibility and control by acting on the grid through innovative advanced power electronics devices, with certain storage management capabilities, and increasing observability of low voltage distribution grids. Specific objectives include:
Â· Design, develop and test a new PMUs and power electronic device to operate the LV grid and provide flexibility through the integration of storage devices.
Â· Enhanced observability of LV grid with wide area monitoring capabilities and early detection of sudden variations in both demand and generation.
Â· Resilient and efficient operation of the LV grid, including optimal configuration based on demand and generation forecasting and providing self-healing capabilities.
Â· Propose and analyse potential and barriers of new business models.
The proposal extends until the integration of software services and new grid infrastructure (PMUs, energy router, etc.) in a data analytics infrastructure, at the same time that assures interoperability with DSO legacy systems (i.e. AMI access, DEM, etc.) and adopts cybersecurity constraints adjusted to stakeholdersâ€™ participation according to specific business models. The European conceptual Smart Grid Architecture Model (SGAM) is being used for interoperability analysis. RESOLVD includes the analysis of potential business models that will make possible the market adoption of RESOLVD technologies in the mid-term. TRL5/6 is expected at the end of the project.
The execution has been split in 9 work packages: WP1(use case and requirement analysis), WP2 (power electronics technologies), WP3 (observability: components and technologies), WP4 (integration and data platform), WP5 (integration and validation -not started-), WP6 (business models and exploitation), WP7(dissemination and communication), WP8 (management) and WP9 (ethics).
During the first 18 months the efforts have been focused on the consolidation of the overall project specifications and starting the development of individual components accordingly. Three milestones have been achieved: MS1: specifications and requirements of RESOLVD solution and technologies, MS2: First prototype of power electronic modules and MS3: RESOLVD platform design.
In WP1, the requirement analysis has been performed by mapping use cases into the different SGAM interoperability layers. Technical actors involved in the RESOLVD architecture have been perfectly identified and their functional, interface and operation requirements have been specified. Analysis cybersecurity threats have been studied according to uses cases and integration issues.
WP2 activities focused on power electronics and storage architecture, design and sizing according to constraints of the proposed relevant scenario. Specific measurement campaigns have been executed. Design specifications of power electronics and a first prototype (laboratory) of the device is available.
WP3 activity has been focused on the network observability specifications. These include field instrumentation (PMUs, Smart metering and other field devices), subsystems (WAMS, SCADA, AMIS) and enhanced DMS functions for the low voltage grid (energy forecaster, critical event forecaster, fault detection, non-technical losses). Synchro-phasor instruments are under development and software components (generation and demand forecasting, enhanced monitoring including fault detection and wide area monitoring and scheduling methods) are under different degrees of achievement.
Activity on WP4 has focused on the design of the software platform (namely the RESOLVD platform) with data management capabilities and integration via ESB (Enterprise Service Bus). Detailed description of its subsystems, interoperability requirements and communication with external systems and services, as well as with the end-users has been reported. Specific tasks for cybersecurity and communication analysis have been started and remain active.
In WP6 major effort has been in identifying exploitation options from the proposed technologies according to business cases identified in WP1. The stakeholders innovation Group (SIG) has been conformed and several actions with them have been carried out.
Sustained communication (WP7) on the web social media (tweeter, LinkedIn, You Tube) and dissemination through publications (scientific) is being maintained. Communication material (videos, poster, flyers, etc.) is available. A sectorial analysis has been started linked to the stakeholders innovation group (WP6).
A total of 25 deliverables have been submitted (M18): WP1 (4), WP2 (2), WP3 (1), WP4 (1), WP5 (not started), WP6 (2), WP7 (4), WP8 (7), WP9 (4).
RESOLVD supposes a step ahead towards LV smart grids, capable of integrating a large share of renewables, with the integration of RES and increasing its hosting capacity by introducing local energy balancing supported by grid storage management and grid scheduling.
Most of the activities until M18 impact on the specification and design of technologies to increase grid observability and automatic energy management capabilities of the LV grid at different levels (switching, phase balance, harmonic filtering, voltage control, local storage, active/reactive compensation).
RESOLVD adopts SotA short-term forecasting methods (random forest algorithms) to infer demand and PV generation at bus level in order to identify possible critical events (congestions and over/under-voltages). A daily grid scheduling of energy resources installed in the LV grid (storage, switching elements) is performed to avoid such critical events, increase hosting capacity and improve energy efficiency (local renewable consumption). Advanced power electronics and LV PMUs are being design to cope with acting observability necessities. Integration of all these technologies aims to report advances on cybersecurity and the identification of lacks of existing smart grid standards when applied to the low voltage grid.
