Robust Control of FACTS for Efficiency and Security of the Electrical Power Network with HVDC Systems
Introduction
The power system represents not only one of the most complex artificial systems in the world, but also one of the most significant ones in modern society. Nowadays, severe consequences have been coursed by large-scale blackouts, such as blackouts in the USA, Europe and many other countries in recent years. Moreover, blackouts not only lead to financial losses, but also lead to potential dangers to society and humanity. So it is necessary to pay attention to planning, design and operation of modern power systems to keep the efficiency and security of the electrical power systems.
Objectives
Our work is concerned with understanding, modeling, analyzing, and mitigating power system stability and control problems that constitute very important considerations in the planning, design, and operation of modern power systems. The objective of my PhD program is to study advanced modeling, control and optimization techniques for power systems, and employ these techniques to improve control performance of systems and stability of power systems. Most importantly, we will investigate the application of robust control theory to the damping of inter-area oscillations in power systems with FACTS devices and batteries and a new robust controller for these devices will be designed with considering the time-delay characteristic to control power flow and enhance the efficiency and security of the electrical power network with HVDC systems.
New FACTS Devices
The following figure shows the topology of the main circuit of the proposed new rectifier system with the new SVC equipment for the custom power system, from which, it can be seen that the new rectifier transformer adopts three-winding structure, and its three winding is connected with the new SVC equipment.
