Objectives The principle objectives of the work will be as follows: Verification that suitable algorithms exist to support the necessary prediction technologies. Identification of suitable condition monitoring equipment which could be used at a demonstrator level Ensure that any future ENCE system fits within existing control room operating protocols Development of a risk register to highlight areas which require further Research or Development activity before deployment of an ENCE system could be considered. Review the potential savings GB wide from the availability of an ENCE system in terms of constraints avoided Clear identification of the best technical approach to take in designing a demonstrator ENCE system Development of a set of criteria to maximize benefit of an ENCE system to the GBSO Identification of the proportion of existing constraints which are thermal, indicating possible future savings from an ENCE system.
Abstract This project investigates how to create a tool which will reliably identify how much capacity will exist in given transmission circuits 48 hours in advance, to allow for appropriate handling of constraint actions and resultant reduction in costs. Research & Development This Technical Development project will examine the underlying technical requirements for a novel new Enhanced Network Capacity system, capable of providing the GBSO with accurate predictions of circuit capability up to 48 hours in advance. We will address the stated Problem through four strands of activity, each targeted on a different aspect of the Enhanced Network Capacity system. Algorithms: A key requirement for the success of the project is the ability to predict what will happen to network conditions (load, temperature etc) between the current time and a given time up to 48 hours ahead. The project will examine a range of different algorithms which may prove suitable for this task. Tests will be conducted against simulated data, built from subsets available from existing data. The necessary granularity of the data would be determined, along with the likely rate at which new data would need to be fed back into the system to refine the predictions. We will conduct a very broad review in order to investigate algorithms which are used to analyse large data sets outside in technology application areas outside of electrical networks. System Monitoring Equipment: The rollout of an Enhanced Network Capacity Evaluation tool across the network would require considerable investment in monitoring equipment to report back to the ENCE system. To determine the appropriate balance between the quality of predictions and reducing the cost of acquiring the necessary data, we will evaluate the minimum possible amount of data required and identify suitable sensing techniques which could be readily implemented into existing communications systems. The feasibility study will concentrate predominantly on transformer and cable assets, drawing on innovation projects underway (e.g. the Twenties NETFLEX project) for overhead line monitoring devices. User Requirements: We will consult widely with System Operations staff to identify the prime user requirements from an ENCE system. This would cover a range of issues from the method of presenting the data visually, through to technical detail such as appropriate ways to handle uncertainties as time to zero moves from 48hrs through to the final system balancing. We will also consult with staff with network development and forward planning roles to ascertain what impacts the availability of such a system (which could provide extra capacity across key boundaries) might have on future capital spend. This process will be enhanced by the provision of demonstration interfaces to further engage staff within National Grid. Computational Architecture & Requirements: Completion of the three previous steps would allow a detailed framework to drawn up of the overall system architecture, with particular identification of relevant data flows. Consideration would be given to a range of approaches, including substation level local processing through local GPUs. The scope would be initially confined to that required to set up a demonstrator in the given target area (see Scope below). A technical risk analysis would be conducted to identify remaining uncertainties in the required computational methods. This approach to the Problem relies uponthe creation of a multidisciplinary project team with skills in power engineering, signal processing & applied mathematics and computing.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
