Meshed offshore grids (MOGs) present a viable option for a reliable bulk power transmission topology. The station-level control of MOGs requires faster dynamics along with multiple objective functions, which is realized by the model predictive control (MPC). This paper provides control, and protection design for the Modular Multilevel...

Given the urgency to shift to a cleaner energy mix, offshore wind energy is bound to be quickly deployed on a large scale in the next years. In order to meet the Paris Agreement, the current role-out rate of wind energy in the North Sea, that is 2 GW/year, needs to be increased to an average value of 7 GW/year over the period 2023-2040. This...

The Manutenção Militar Complex (MMC) is situated along the river just outside of the city center of Lisbon. Within the industrial complex they produced food, uniforms and other goods for the Portuguese Army. Whilst the Portuguese Army reached 200,000 men in the 1960s, it is now reduced to 20,000 active soldiers. This meant that the factories of...

The MMC was an industrial facility that produced food, uniforms and other goods for the Portuguese Army. During the twentieth century the complex was expanded. Whilst the Portuguese Army reached 200.000 men in the 1960’s, it is now reduced to 20.000 active soldiers. Gradually the factories closed and Manutencao Militar was finally substituted by...
