Nietzsche and Montaigne: cheerful naturalism

The influence of the Essays of Michel de Montaigne on the thought of Friedrich Nietzsche has, hitherto, received scant scholarly attention. The aim of this thesis is to address this lacuna in the literature by making evident the importance of the Essays to the development of Nietzsche’s philosophy. I argue that, in order to fully appreciate Nietzsche’s thought, it must be recognized that, from the beginning to the end of his philosophical life, Montaigne was for him a thinker of the deepest personal and philosophical significance. Against the received scholarly opinion, which would see Montaigne as influential only for Nietzsche’s middle works, I contend that the Essays continue to be a key inspiration for Nietzsche even into his late and final works. Montaigne, with his cheerful affirmation of life, his experimental mode of philosophizing, and his resolutely naturalized perspective, was an exemplar for Nietzsche as a philosopher, psychologist, sceptic and naturalist. The Essays not only stimulated Nietzsche’s thinking on questions to do with morality, epistemology and the nature of the soul but also informed his conception of the ideal philosophical life. Moreover, to explore the Essays from a Nietzschean viewpoint, allows the drawing out of the more radical aspects of Montaigne’s thought, while to probe Montaigne’s impact on Nietzsche, provides insight into the trajectory of Nietzsche’s philosophy as he broke free from romantic pessimism and embraced the naturalism that would guide his works from Human, All Too Human onward.

Cost savings from relaxation of operational constraints on a power system with high wind penetration

Wind energy is predominantly a nonsynchronous generation source. Large-scale integration of wind generation with existing electricity systems, therefore, presents challenges in maintaining system frequency stability and local voltage stability. Transmission system operators have implemented system operational constraints (SOCs) in order to maintain stability with high wind generation, but imposition of these constraints results in higher operating costs. A mixed integer programming tool was used to simulate generator dispatch in order to assess the impact of various SOCs on generation costs. Interleaved day-ahead scheduling and real-time dispatch models were developed to allow accurate representation of forced outages and wind forecast errors, and were applied to the proposed Irish power system of 2020 with a wind penetration of 32%. Savings of at least 7.8% in generation costs and reductions in wind curtailment of 50% were identified when the most influential SOCs were relaxed. The results also illustrate the need to relax local SOCs together with the system-wide nonsynchronous penetration limit SOC, as savings from increasing the nonsynchronous limit beyond 70% were restricted without relaxation of local SOCs. The methodology and results allow for quantification of the costs of SOCs, allowing the optimal upgrade path for generation and transmission infrastructure to be determined.
