Electrical grid1/1/2024 ![]() Modeled after the hierarchical control architecture of power transmission systems, a layering of primary, secondary, and tertiary control has become the standard operation paradigm for microgrids. Microgrids are able to connect to a larger electric power system, but are also able to island themselves and operate independently. Microgrids are low-voltage electrical distribution networks, composed of distributed generation, storage, load, and managed autonomously from the larger transmission network. ![]() With the goal of integrating distributed renewable generation and energy storage systems, the concept of a microgrid has recently gained popularity. Rather than fixing the control structure a priori, our work employs the recently-introduced paradigm of sparsity-promoting optimal control to simultaneously identify the optimal control structure and optimize the closed-loop performance.ĭistributed control and optimization in microgrids Since inter-area oscillations are typically poorly controllable by means of local control, recent efforts have been aimed at developing wide-area control strategies that involve communication of remote signals. We follow the slow coherency approach based on identifying and aggregating sparsely and densely connected areas of a network, within which all generators swing coherently. To tackle the complexity of inter-area oscillations for analysis, control design, and monitoring schemes, it is of interest to construct reduced-order models which preserve the dynamics of interest. In this project, we are interested in the electromechanical inter-area oscillations, which are associated with the dynamics of power transfers and involve groups of generators oscillating relative to each other. To create the Grids and Storage Criteria, we convened a Technical Working Group (TWG) and an Industry Working Group (IWG) with representatives from investors, public entities, research institutes and international policy bodies from around the world.A power network is a large-scale and complex dynamical system combining both the rich dynamics of the individual subsystems as well as their non-trivial interaction through the network. The Grids and Storage Technical and Industry Working Groups (TWG and IWG) Improved guidance, such as these Grids and Storage Criteria, will catalyse investment and can be utilised by governments in setting regulation or recommendations for decarbonising the sector. However, global investment has been falling for the past several years, down from USD 306 billion in 2016 to USD 248 billion in 2020. The dependence of so many sectors and societies on stable electricity provision makes grid resilience essential.Įstimates suggest investment in electricity networks needs to increase from 16% of total energy investment to 19% between the years 2025 – 2030 to meet the Paris goals. This is all while ensuring this infrastructure is adapted to changes in climate. For industrial sectors or buildings, electrification is a key means to achieving decarbonisation. ![]() At the same time, this infrastructure is vital for the decarbonisation of other sectors. More flexible and distributed systems are needed to bring about clean electricity. ![]() Why develop eligibility Criteria for grid- and storage-related low carbon investments?Įxpanding and upgrading electricity grid and storage infrastructure is crucial to meeting the steep decarbonisation goals for energy systems. Public consultation for the Grids and Storage Criteria has now ended.Ī webinar took place on Tuesday 8th June 2021 that provided an opportunity for interested parties to learn more about the Criteria and to ask our lead technical consultant Ian Walker and staff at CBI any specific questions they might have: The Grids and Storage Criteria contain both Mitigation Requirements and Adaptation & Resilience Requirements.īonds and loans linked to these eligible assets and projects will be aligned with the Paris Agreement 1.5 oC limit. The Criteria apply to transmission, distribution and storage of electricity. Status: The Grids and Storage Criteria are now available for use for certification.Ĭriteria: The Grids and Storage Criteria lay out the requirements that grid and storage assets and/or projects must meet to be eligible for inclusion in a Certified Climate Bond.
