“…In [8] the consequences of the ambitious plans of the German "Energiewende" for extending the transmission grid to cope with huge shares of renewable production are analysed by means of a new combination of a power grid model, an energy system model and a unit commitment model representing production decisions. The study shows that the planned extensions are likely sufficient to avoid congestions and overloads in plausible future production scenarios even in the single-line outage case.…”

“…These papers can be roughly grouped into five categories, namely, surveys [1][2][3][4] prediction and volatility of renewable infeed [5][6][7] derivation of requirements for a resilient power grid infrastructure [8][9][10][11][12][13] relationships between grid stability and complex network topology [14][15][16][17] and the analysis of special issues in dynamic stability [20][21][22]. Because of the various overlaps, we still chose to assemble these works in alphabetical order in this volume.…”

Abstract. This topical issue collects contributions to the interdisciplinary study of power grid stability in face of increasing volatility of energy production and consumption due to increasing renewable energy infeed and changing climatic conditions. The individual papers focus on different aspects of this field and bring together modern achievements from various disciplines, in particular complex systems science, nonlinear data analysis, control theory, electrical engineering, and climatology. Main topics considered here are prediction and volatility of renewable infeed, modelling and theoretical analysis of power grid topology, dynamics and stability, relationships between stability and complex network topology, and improvements via topological changes or control. Impacts for the design of smart power grids are discussed in detail.Many countries face the problem that reducing greenhouse gas emissions while phasing out nuclear energy requires a transformation of the energy system that includes large amounts of renewable energy production. The latter, however, is highly influenced by extreme weather events, which are likely to get more frequent and more severe due to climate change. Extreme events influence not only the availability of energy, but also and of more fundamental importance, the stability of the whole power grid, which is not yet understood sufficiently. Grid operation and control will profit a

“…Typically, renewable power sources are strongly fluctuating, have a lower power output than conventional ones, and their potential geographical locations are restricted to places with sufficient solar or wind power [1,2]. This development is challenging the operation and stability of electric power grids: power has to be transmitted over long distances [3], fluctuations must be balanced by storage or backup power plants [4][5][6], and many decentralized units must be controlled [7][8][9].…”

“…Each of these outages affected millions of people with potentially destructive impact [14,15]. It is commonly expected that the loads will increase strongly in future grids [3], so that these outages can become more likely. So it is urgent to trace back what causes such outages and to minimize the risk for these events to happen in the future.…”

Curing critical links in oscillator networks as power flow models

Modern societies crucially depend on the robust supply with electric energy so that blackouts of power grids can have far reaching consequences. Typically, large scale blackouts take place after a cascade of failures: the failure of a single infrastructure component, such as a critical transmission line, results in several subsequent failures that spread across large parts of the network. Improving the robustness of a network to prevent such secondary failures is thus key for assuring a reliable power supply. In this article we analyze the nonlocal rerouting of power flows after transmission line failures for a simplified AC power grid model and compare different strategies to improve network robustness. We identify critical links in the grid and compute alternative pathways to quantify the grid's redundant capacity and to find bottlenecks along the pathways. Different strategies are developed and tested to increase transmission capacities to restore stability with respect to transmission line failures. We show that local and nonlocal strategies typically perform alike: one can equally well cure critical links by providing backup capacities locally or by extending the capacities of bottleneck links at remote locations.

“…Besides distributed generation, demand response, and new or upgraded transmission lines, energy storage is expected to foster the balancing of the power system (e.g. [1][2][3][4][5][6]). In this context, power-to-gas (P2G) is a relatively new concept which enables to transform surplus power to hydrogen by electrolysis or even to renewable methane by additional methanation (e.g.…”
