Voltage Regulation Of Low Voltage Distribution Networks, Manisha Maharjan
Electronic Theses and Dissertations
The modern voltage distribution systems consist of distributed generation (DG), like photovoltaics (PV) and wind. These resources are inexhaustible and environmentally friendly. The existing low voltage (LV) distribution networks are typically designed for unidirectional power flow. The integration of DG makes the LV distribution networks prone to difficulties related to voltage, frequency, and power quality. The main challenges in the integration of DG occur due to the intermittent nature of DG. The amount of DG compared with the total generation resource on a power system network is measured as penetration. The system undergoes through reverse power flow when there is …

Intelligent Learning Control System Design Based On Adaptive Dynamic Programming, Naresh Malla
Electronic Theses and Dissertations
Adaptive dynamic programming (ADP) controller is a powerful neural network based control technique that has been investigated, designed, and tested in a wide range of applications for solving optimal control problems in complex systems. The performance of ADP controller is usually obtained by long training periods because the data usage efficiency is low as it discards the samples once used. Experience replay is a powerful technique showing potential to accelerate the training process of learning and control. However, its existing design can not be directly used for model-free ADP design, because it focuses on the forward temporal difference (TD) information …
