Abstract [en]

Congestion is a major limiting factor preventing expansion of renewable energy production in distribution networks. However, with large shares of connected power electronic-interfaced generators in combination with new types of controllable loads, such as electric vehicles (EVs), there is a potential to greatly increase network operation flexibility. Utilising these available flexible resources effectively is crucial to boost network capacity in a cost-effective manner and allow for safe integration of additional renewable energy sources (RESs). In parallel, the reactive power flows in distribution networks are changing. This can be attributed to the increased RES production and increased charging currents due to expanding cable networks. Also contributing to the changing flows is the rising number of new household appliances and consumer electronics with non-linear load characteristics. This makes systemwide coordination of resources an even more pressing issue. For distribution system operators (DSOs), minimising undesired reactive power flows at the connection to the transmission system is key to meet inter-network requirements. In this paper we propose a centralised near real-time control algorithm for combined congestion management and reactive power control in distribution networks. Through updated communication and measurement protocols, together with more extensive use of the active and reactive power control capabilities of local flexibility resources – such as wind power plants (WPPs), photovoltaic (PV) units, and flexible loads – bottlenecks can be detected and eliminated. Flexibility is offered by local resources and dispatched by the DSO through a common platform, which is independent of any specific financial arrangement for the participating flexibility providers. Thus, market solutions and individual contractual agreements are not mutually exclusive and can be implemented in parallel. The inclusion of reactive power simplifies the DSO’s coordination of intra-network and inter-network operational requirements. We demonstrate selected algorithm features through simulations of a congestion scenario in a medium voltage benchmark network. Aspects of deploying the solution in actual distribution network operation are also outlined.

Abstract [en]

The Joint Working Group C4/C2.58/IEEE was established to review voltage stability of power systems in the context of increased penetration of Inverter Based Resources (IBR) in electric power grids. The focus was to evaluate the adequacy of existing methods of voltage stability assessment in the present-day context. The developed technical brochure reviewed the definition of voltage stability and explained the role of voltage stability assessment within the voltage security assessment task of near real time power system operation. The overall conclusion is that the controllers implemented on IBRs makes a significant influence on short-term, but also long-term voltage stability. The presence of IBRs at distribution voltage levels contribute to the dynamic behavior of the power grid. Voltage stability assessment must incorporate these facts to ensure that the methods and tools accurately capture voltage stability limits.

Abstract [en]

Power system resilience is an overarching concept covering the whole spectrum of the power system, from design and investment decisions to planning, operations, maintenance and asset management functions. Flexibility concerns the power system's ability to manage changes, with flexibility features able to improve the resilience characteristics of the system, provided that they are integrated into grid planning, in defence plans, and evaluated adequately in the energy market design. An analysis of ongoing worldwide initiatives provides relevant insight into ongoing worldwide initiatives. They provide relevant insight into how flexibility can support resilience, showing the prominence and potential values that can be unlocked, with potentially some low-hanging fruits to start. This paper introduces four innovative concepts: Alternative grid development, system integrity protection schemes, the next level of flexibility and LINK holistic approach to flexibility for resilience as solutions contributing to improving future power systems' resilience.

Abstract [en]

This Technical Brochure explores the integration of Wide Area Monitoring (WAM) and Wide Area Monitoring, Protection, and Control (WAMPAC) systems into decision support tools for control room processes of modern power systems. It highlights the need for synchronised measurement technologies as provided by Phasor Measurement Units (PMU) to observe and control the electrical grid effectively. The brochure discusses various applications and timeframes for decision-making processes using synchrophasor measurements, ranging from real-time control to post-event analysis. By sharing practical experience, it emphasizes the challenges and benefits associated with deploying WAM and WAMPAC systems into standard control room procedures and provides recommendations for areas of further research and development.

Abstract [en]

This paper will provide insights regarding the financial implications of non-conventional grid development solutions, which are intended to provide agile, flexible and supportive solutions and thereby enable a sustainable development of the power system. As complements to traditional grid expansion developments, Active Network Management (ANM) solutions provide new methods to plan and operate the power system. In the case of long-term investment planning, different grid development solutions are weighed against each other based on e.g., their resilience, cost, environmental impact, and time to operation. The results presented in this paper originate from the ongoing European research project ANM4L [1]. While the developments in the ANM4L project are based on three pillars (ANM control solutions, Business solutions, & ICT solutions), the activity in focus of this paper is on the discussion on necessary investment decisions by the DSO and whether to continue traditional operations or to apply ANM solutions. The pillars of the ANM4L project are collectively resulting in a toolbox developed to support the operation and planning of distribution grids, which functionality and replicability will be tested and demonstrated within the ANM4L project. The activity in focus of this paper lies within the second pillar and is on the discussion on necessary investment decisions by the DSO and whether to continue traditional operations or to apply ANM solutions.
