Hardware-in-the-Loop Power Distribution Testbed for Control and Security
Abstract
Project Title: Hardware-in-the-Loop Power Distribution Testbed for Control and Security Funding Opportunity Title Fiscal Year 2015 Defense University Research Instrumentation Program (DURIP): PA-AFOSR-2014-0001 Investigators: Saroj K. Biswas and Li Bai Electrical and Computer Engineering College of Engineering Temple University Philadelphia, PA19122 Summary: Modern power grid architectures including those of naval interests are expected to be integrated DC and AC systems and machines along with their associated communication network for data transfer for command and control. The networked nature of such critical infrastructure which facilitates their effective and efficient operation also renders them vulnerable to attacks in cyber domain as well as to faults in the physical domain. The challenges of power distribution control and security significantly differ from classical power grid due to: synergies between heterogeneous yet interdependent cyber and physical subsystems, and the need for control and security solutions applicable for their efficient operation. This project focuses on the development of a testbed for stability analysis, control design and security analysis of integrated AC/DC power distribution system in the presence of pulse load, pulse generation, and hybrid and renewable energy sources in addition to traditional power system elements. The proposed testbed will be implemented as a hybrid system of interconnected hardware and software. In particular, distribution system will be simulated in software using OPAL-RT which will be interfaced with various power hardware, such as generators, induction motors, power converters and inverters, and traditional DC and AC loads. Overlaid on the power network will be a communication network with various sensors for data transmission and control interface. The overall architecture of the testbed will be reconfigurable and scalable. In recent years, securing critical infrastructure such as the power grid has emerged as a major national and global priority. In this context, our focus is security of control system and sensor network associated with various electrical machines and the distribution system. The testbed will have the option to simulate cyberattacks on the sensor network and to induce delays and packet drops in the overlaid communication network. The developed testbed provides an experimental platform for analyzing overall stability performance of the power network in the event of a component failure or control system failure due to cyberattack as well as due to a physical breakdown.
