Integrid - Bridging the Gap

13 takes into consideration net-load and solar photovoltaic forecasts for a predefined horizon to define a series of control actions to reserve flexibility to prevent technical problems and to act in the case of real-time operation by using the pre-booked flexibility. HLUC03 - Perform asset health diagnostics for preventive maintenance This HLUC aims at using big-data analytics along with intelligent scheduling techniques to improve distribution-grid reliability indexes. As more information is expected to be collected from advanced metering infrastructures, supported by the integration of information and communication technologies, an active posture towards preventive management will be possible. The goals of this HLUC are to increase distribution grid reliability, avoid fatal errors, reduce maintenance costs, and postpone unnecessary local maintenance tests by using big data analytics with event-driven maintenance for self-monitored equipment. HLUC04 - Operation plan repair of unplanned outages based on remote diagnostics and historical data The main objective of this HLUC is to develop a process to optimize restoration and repair actions of unplanned outages based on pre-fault data collected from sensors, on remote equipment diagnostics, and on historical data collected from smart secondary substations. An historical database will be used with details of past interventions, thus enhancing the awareness of decision makers. Unplanned outages can be caused by incidents such as traffic accidents or power line damage due to snowstorms and/or high winds, etc. The estimated result is a reduction in the outage time and consequently an improvement in the distribution network continuity of service indexes, such as SAIDI and CAIDI. HLUC05 - Managing the impact of flexibility activation from resources connected to the network In this Use Case, the TSO is contracting flexibility products on the balancing market. These flexibilities are provided by resources connected on the distribution grid and therefore their behaviour directly affects the state of the network. For instance, the shedding of loads in order to provide upward reserve has a direct impact on the voltage profiles of the feeder where the loads are located and in the event that the contracted volume of reserve is too large, the upper voltage limit can be exceeded. Therefore, a technical validation of flexibility products by a Neutral Market Facilitator is necessary in order to ensure safe and reliable network operation. HLUC06 - Provide data management and exchange between DSO and stakeholders This high-level Use Case describes the functional process of the grid and market hub services provided by the DSO to stakeholders. The DSO provides anonymized and pre-processed metering data to external stakeholders in order to promote new data driven services provided by market entities with benefits for distribution grid users and market actors such as: i) provision of data on ToU / dynamic network tariffs for customers, suppliers, aggregators, leading to end use flexibility; ii) provision of information to LV consumers on their peak demand in order to increase the threshold or the effective use of contracted power to incentivise them to reduce peak demand; iii) provision of data to customers or 3 rd parties with explicit consent from customers; iv) provision of information on abnormal consumption patterns or energy consumption above a threshold defined by the consumer. HLUC07 - Procure and manage regulated flexibilities from DER to optimize operation and costs This HLUC consists of two main steps occurring at different times: i) In the first stage, the DSO aims to pre-qualify potential flexibility providers/operators ensuring that they can technically provide the service needed and define the terms and conditions of the flexibility contracts signed with them. This step requires a techno-economic validation of the service providers and a pre-assessment of network areas to determine where and when the services are needed. This first stage happens before the time at which distribution grid operational planning takes place (usually between one week and one day ahead of real- time operation); ii) In the second stage, the DSO seeks to activate the flexibilities previously contracted when
