The application of the power electronics in the electrically transmission systems (Power Electronics Control / PEC) is coming out as a necessity to serve the rapid growth in Demand Side Management (DSM),. The energy produced in the renewable generation systems, which are mainly based on the renewable energy resources, needs to be appropriately distributed to the different loads and energy distribution systems. It is very important in the distribution system that the voltage/power and current are kept well regulated and also to reduce the harmonic distortion of the power. It also used to be very important to control the line currents of the electric power system for load balancing and also to maintain the voltage of the system under the normal conditions even in the presence of the fault in part of the transmission section. The document also specifically addresses the Linear Phasor Modulation (LPM) system, which is a very important technology for the distribution of the renewable energy generated from the renewable generation systems. The document also specifically addresses the ripple control of the LPM system, voltage control with demand side management and stability in the distribution system.
The development and modelling of a complete flywheel system is a very ambitious objective for the propose of the thesis. Therefore, it was considered that the system should be modular and manageable. The basic units of the system are synthesised based on the needs of the system and their performances are analysed. The following are the basic modules of the system: 1) Each module provides the environmental, physical and electrical characteristics proportional to the scale of the respective unit and 2) Each module has a control interface for the external control units. The control interface can read the measured characteristics and the interface can send the required parameters to the respective controller for control.
e) The Safety and reliability design requirements are addressed in the design and use of the charge controller. The charge controller should be designed such that the energy stored in the battery is discharged to the consumer at a controlled rate from the battery (when the necessary energy is not available from other alternatives). An effective way to accomplish this is to use a regulator with a constant switchiing voltage drop and an efficient full-charge-recharge function. d2c66b5586
