The high proportion of grid-connected intermittent energy such as wind power and photovoltaic makes the demand for power system flexibility increase sharply. In order to improve the overall flexibility of new energy high permeability system and enhance the economy of power system, promote the new energy consumption of system. This paper presents a multi- time scale Coordinated optimization strategy for the new energy high permeability power system considering flexibility requirement (MTS...
A modeling with a good predictive rate is necessary to create a good performance of the predictive controller . The correct and better model to use is the Predictive Control Model (MPC) or the Predicted Control Model. This study determines the control optimization system with the Predicted Control Model for the plant of Multi Input Single Output (MISO). The MPC optimal control system designed for the closed-loop Mismatch method, the effect of changes in the Kalman amplifier state estima...
The life of a transformer is associated with the state of the insulation system, one of the techniques used to measure the insulation system is frequency-domain spectroscopy (FDS), which measures the dielectric properties in the frequency domain. This work establishes a mathematical model with the data of the FDS to estimate the parameters of the equivalent circuit of the dielectric response of the paper-oil isolation system of the transformer, which is a group of non-linear eq...
