Low-frequency oscillations are a primary issue for integrating renewable source into the grid. The objective of this study was to find sensitive parameters that cause low-frequency and design Twin Delayed Deep Deterministic Policy Gradient (TD3) agent controller damp without requiring an accurate system model. In work, Q-learning (QL)-based model-free wind speed DFIG designed on rotor-side conv...

in this paper smart operation of micro energy hub is presented. energy hub system consists of certain energy hubs and interconnectors that are coordinated by energy hub system operator. an energy hub contains several converters and storages to serve demanded services in most efficient manner from available energy carriers. in this paper, the flexibility of energy delivery point is enhanced u...

the abrasion is a significant issue, especially in machining of rigid steels. a functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. the objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...

The multi—pulse excited linear prediction (MPELP) system is proposed for speech enhancement. It is shown that for successful enhancement of speech the error—weighting filter should not be used in the MPELP system. A new method (the constrained forward—backward correlation prediction method) is proposed for accurate estimation of LP coefficients from noisy speech. This method guarantees the stab...

The gas turbine synchronous generators (GTSGs) are widely deployed as distributed generations (DGs) in countries with massive natural production owing to their low prices. However, due the inertia time constants of these synchronous-based DGs, they more susceptible power grid faults which stands a transient stability issue networks multiple microgrids (MGs). On other hand, cloud energy storage ...
