The high penetration of renewable energy into distribution networks poses increasing challenges on voltage control. To address this issue, paper presents a double-layer stochastic model predictive control algorithm to regulate profile in active networks. In the proposed algorithm, regulation is achieved by coordination an upper layer controller and lower controller. layer, number operation mech...

This research will demonstrate feasibility for manufacturing fiber-based ceramic capacitors suitable for electrical energy storage within multifunctional textile products. Capacitive energy storage is well matched to applications requiring high specific power, long cycle life, and high reliability. We are using a simple chemical scheme for preparing fiber-based capacitors by coating electricall...

Various models leading to predictions of negative capacitance, C, are briefly reviewed. Their relation to the nature of electric control is discussed. We reconfirm that the calculated double layer capacitance can be negative under σ-control an artificial construct that requires uniform distribution of the electrode surface charge density, σ. For instance, It is shown that the combined relaxatio...

In this note, small amplitude free vibration of a double-beam system in presence of inner layer nonlinearity is investigated. The nonlinearity is due to inner layer material and is not related to large amplitude vibration. At first, frequencies of a double-beam system with linear inner layer are studied and categorized as synchronous and asynchronous frequencies. It is revealed that the inner l...

The self-discharge of an electric double-layer capacitor with composite activated carbon electrodes and aqueous electrolyte (1 M MgSO4) was studied in detail. Under a long-term potentiostatic charge (stabilization), decrease the discharge capacity observed region voltages exceeding 0.8 V. process consists two phases. In initial phase, cell voltage drop is due to redistribution inside electrodes...
