| Objectives | The project will be structured into six distinct work streams (WS):WS1: Identify and review current ANM schemes on the transmission (e.g. Generation Export Management Scheme (GEMS) used in Dumfries and Galloway) and distribution networks and their impact on T&D coordinated activities. Analyse their associated technical and commercial requirementsWS2: Develop test cases and high-level assessment of potential benefits of these test cases. Evaluate the ability of DERs to participate in ANM activities and develop network case studies reflecting different types of ANM schemes and the potential synergies and conflicts of DERs participating in ANM activities.WS3: Identification and definition of solutions to optimise coordination of ANM schemes and ESO balancing services marketWS4: Perform a cost benefit analysis of the coordinated ANM case studies through modelling and simulation. Identify limitations imposed by commercial frameworks.WS5: Delivery plan for practical deployment of feasible solutions. Analysis of the simulated case studies, synthesis of key findings and identification of whole system principles of operation and control hierarchies for T&D.WS6: Identify and develop a set of recommendations, produce a report and disseminate findings. National Grids Future Energy Scenarios (FES) and System Operability Framework (SOF) show that the installed capacity of Distributed Generation (DG) has increased to 31GW in 2018 and is set to rise to a level of 38 – 69GW by 2030 across all FES scenarios. This significant growth of DG together with the development and adoption of smart grid technologies means that network operators, both transmission and distribution, have the need and the means to more actively manage flows on their networks. Thus, network operators are introducing Active Network Management (ANM) schemes to manage network assets, generation and demand dynamically in real time to increase the utilisation of network assets without breaching operational limits, reduce the need for reinforcement, speed up connection timelines and reduce costs.As network operators (most notably Distribution Network Operators (DNOs)) start taking a more active role in managing flows on their networks, greater collaboration and coordination with the Electricity System Operator (ESO) is required to efficiently manage the overall power system.The SOF shows that there is an increasing number of constraints on DNO networks that are likely to be managed by ANM systems over the next five years. Meanwhile, wider access to the Balancing Mechanism has been introduced and the ESO is increasingly procuring ancillary services from Distributed Energy Resources (DER). Without coordination of activities between the ESO and network operators, there is potential for: ANM schemes to counteract the ESOs balancing actions or to cancel out the effect of system services (e.g. STOR, DSR) procured from DER DER connected to ANM arrangements to be unnecessarily blocked from participation in balancing services markets Both could lead to increased costs to the consumer and pose a risk to security of supply if system services are not delivered when required.Opportunity for optimal coordination between ANM approaches and balancing servicesTo this end, there is a need to deliver an optimally coordinated design approach between ANM schemes and balancing services markets. It is critically important to ascertain and understand the synergies and conflicts associated with the potential forANM schemes in networks inhibiting the delivery of ESO system support services through DER. Hence, this project proposes to: Engage collaboratively with the ESO and the DNOs to understand: the range of existing ANM schemes and volumes of DER connected downstream of constraints managed by ANM schemes; and the restrictions placed on the participation in balancing services markets of DER connected behind constraints which are managed by ANM schemes under existing commercial arrangements. Identify issues which could arise from the participation in balancing services markets of DER connected downstream of constraints which are managed by ANM schemes; Evaluate the potential for DER connected downstream of an ANM managed constraint to participate in balancing services markets in a coordinated manner; Identify and define different approaches to coordinating ANM schemes with balancing services markets and their associated technical and commercial requirements; Quantify and assess the costs and benefits of the different approaches to coordinated ANM schemes from the perspective of whole system techno-economic efficiency to determine the optimal coordination approach(es); Identify a way in which that optimal coordination approach can be delivered through identification and proposed resolution of limitations and barriers in the existing approaches and commercial frameworks; and Develop whole system principles of operation and control hierarchies for the procurement of system services from DER in order to inform the development of best practice guidelines for delivering whole system coordination in respect of other services procured in the future. The key objectives of this work can be described as follows: To identify and define different optimal T&D coordinated ANM schemes, their associated technical and commercial requirements as well as compatibility with existing industry codes and regulatory frameworks; To develop test cases and evaluate the ability of DER to participate in the ANM functions of the distribution system or in whole system balancing actions in a coordinated manner; To identify and define solutions that will optimize the coordination of ANM schemes with the balancing services market; To develop a delivery plan for deployment of the solutions To disseminate findings and recommendations to other network licensees. | |
