A novel real time approach structure implementation to manage multiple sources and/or generator systems on supporting the global load, in case of charge and functioning disturbances is proposed. Its applicability is validated on a control structure of two and four constant and variable load sources (with parallel connection), a situation usually encountered these days in the renewable energy branch...
Shifting towards higher penetration of diverse renewable energy sources (RESs) in power systems is motivated mainly by reducing carbon emissions. In the long term of several decades, which we refer to in terms of the future grid (FG), balancing between supply and demand will become more challenging. Also, displacing conventional generators with RESs, especially inverter-based and intermittent RESs,...
In this paper, a multi-step simulation tool for the evaluation of operation strategies with predictive concepts for controllable distributed generators is proposed and applied exemplarily to perform an annual simulation of a sewage gas CHP trading at a power exchange. The analysis quantifies the disturbing effect of prediction errors as compared to a simulation without predictive elements. The simulation...
Due to limited predictability of variable renewable energy sources such as wind energy, the balance between demand and supply in electricity systems is challenged. Market players integrating these technologies in their portfolio face increasing imbalances and are, consequently, charged with cost-reflective imbalance tariffs. In this paper, an optimization model is developed which aims to minimize...
Replacement of conventional power plants by RES generation requires future involvement of the new generators also in the fields of power balancing and ancillary services. Nowadays, small and medium-size CHP as decentralized generators with a significant potential for demand driven electricity production do not provide such services in most European countries. In contrary: implemented incentives like...
STT-MRAM has emerged as a compelling candidate for universal memory, but demands an advanced sensing circuit to achieve the proper sensing margin. In addition, STT-MRAM requires low-current sensing to avoid read disturbance. We report a novel sensing circuit that utilizes a source degeneration scheme and a balanced reference scheme. Monte Carlo HSPICE simulation results using 65 nm technology model...
