Optimizing Renewable Power Management in Transmission Congestion. An Energy Hub Model Using Hydrogen Storage
2021
Energy production from distributed renewable power plants underwent a takeoff in last years as never before. Nevertheless, the installation of technologies based on variable energy resources and their connection on transmission power lines might cause congestions due to the transmission capacity limits. This paper describes the modelization of a HV transmission line with local renewable production and its optimal management through an Energy Hub model. Aim of the study is to identify the optimal size of the power storage, based on an electoryzer, a hydrogen storage and a fuel cell, in order to minimize the congestion risks and to maximize the exploitation of renewable energy production.
ES enerģētikas diplomātija: veids, kā orientēties enerģētikas jomā Zaļā darījuma laikmetā
2021
The European Green Deal encompasses two aspects spanning across the internal-external continuum. Firstly, to achieve climate neutrality, the EU energy sector will undergo a complete transformation and, consequently, play an essential role in the bloc’s transition to a cleaner economy. Secondly, the Green Deal provides the EU with an impeccable opportunity to play a more assertive role in international politics. In this context, energy diplomacy becomes a vital tool for the EU’s objectives. The papers argue that energy diplomacy can help the EU respond to its overall energy situation. In order to answer the research question, first, the EU energy situation has been systematically studied thr…
Pd-Co-Based Electrodes for Hydrogen Production by Water Splitting in Acidic Media
2023
To realize the benefits of a hydrogen economy, hydrogen must be produced cleanly, efficiently and affordably from renewable resources and, preferentially, close to the end-users. The goal is a sustainable cycle of hydrogen production and use: in the first stage of the cycle, hydrogen is produced from renewable resources and then used to feed a fuel cell. This cycle produces no pollution and no greenhouse gases. In this context, the development of electrolyzers producing high-purity hydrogen with a high efficiency and low cost is of great importance. Electrode materials play a fundamental role in influencing electrolyzer performances; consequently, in recent years considerable efforts have b…
Optimizing the generation system in a microgrid with power, thermal energy and mobility demands
2021
Microgrids are widely known to be the future of generation and distribution systems. This paper presents a method to optimize the size of the main components in a microgrid to supply the demands for electricity, heating and hydrogen for mobility through an Energy Hub model. The electricity production from a wind turbine, a CHP and a fuel cell satisfies the local electricity demand. The green hydrogen produced in the hub from renewable power in off-peak hours is used to feed the fuel cell or to meet the mobility demand. The heating power from CHP and fuel cell is used to feed the local district heating network.
