Software security for critical infrastructure, such as electrical grid and SCADA systems is becoming an increasing important issue. Fuzzing techniques are widely used to detect software security vulnerability, from various approaches (mutation-based or grammar-based, blackbox or whitebox) depending on the information used to generate test input. Although existing studies have advantages, they also...
The ever increasing integration of renewable energy resources into the electric energy system gives rise to new challenges on a large scale. New and extended information technology is necessary for controlling the corresponding power grids and their components. The need for advanced control functions and ancillary services provided by distributed energy resources is also increasing. As a response...
Electric power grids are undergoing a modernization process. By relying on the ICT infrastructure and on Internet connectivity, these so-called Smart Grids are now able to provide new functionalities and to become more efficient. However, despite the existence of a few standards that aim to specify the secure operation of Smart Grids, utility companies do not have a comprehensive set of metrics and...
Smart Grid, Smart Metering, Electromobility and the regulation of the power network are keywords of the transition in energy policies. In the future, the power grid will be smart. Due to this the OTH Regensburg does research in this area based on different projects. This paper presents a data collection, analyzing and monitoring software for a reference Smart Grid. We discuss two possible architectures...
Malware can spread uncontrollably if left unchecked and can cause significant damage to the Advanced Metering Infrastructure (AMI) and ultimately to the underlying power grid. Application layer protocols used in the AMI are capable of carrying large payloads which could be potentially used to hide malware. Fortunately, application layer traffic in the AMI is not expected to contain executable content...
Supervisory Control and Data Acquisition (SCADA) system play the most important roles in the remote surveillance system. The development of the communication system of the new substations such as renewable energy sources, smart grid houses, new energy sources in power network, increases the nodes in a data communications network, which increases the number of possibilities to connect to the SCADA...
Smart grid, the future power grid, is expected to provide better energy efficiency, more customer choices and improved reliability and security. As the smart grid is an integrated system that consists of multiple subsystems, understanding it as a whole system is required to fully understand the security risks it faces. In this paper, a sophisticated cyber-physical system (CPS) unique malware attack...
This paper describes the design of a modular hard-and software platform for the implementation of an intelligent charging infrastructure for electric vehicles. This infrastructure implements intelligent control of charging processes with respect to the local and global grid situation, for instance. Today, there are many solutions for intelligent charging infrastructures, which were developed in several...
Several countries have invested in technologies for Smart Grids. Among such protocols designed cover this area, highlights the DNP3 (Distributed Network Protocol version 3). Although the DNP3 be developed for operation over the serial interface, there is a trend in the literature to the use of other interfaces. The Zigbee wireless interface has become more popular in the industrial applications. In...
The development of a smarter electric grid will depend on increased deployments of information and communication technology (ICT) to support novel communication and control functions. Unfortunately, this additional dependency also expands the risk from cyber attacks. Designing systems with adequate cyber security depends heavily on the availability of representative environments, such as testbeds,...
We address the potential for a truly universal set of integrated wireless communication services, energy management, and control services for a next-generation of National Institute of Standards and Technology microgrid standards. Our approach uses cloud computing data center as the central communication and optimization infrastructure supporting a cognitive radio network of AMI meters which we label...
Electricity losses during transmission and distribution are extremely high in India. One of the principal reasons for this is the presence of non-technical energy losses (NTL), that is, energy losses caused due to theft, meter malfunction, etc. Identifying non-technical energy losses is an open research problem and various methods are being proposed to deliver an optimal solution for the same. The...
Demand response (DR) is becoming an increasingly important part of power grid planning and operation. The advent of the Smart Grid, which mandates its use, further motivates selection and development of suitable software protocols to enable DR functionality. The OpenADR protocol has been developed and is being standardized to serve this goal. We believe that the development of a distributable, open...
Concepts for future energy networks envision the distribution of measurement and control infrastructures to the customers to allow for improved reactions to certain events in the energy grid and to ease the measurement process. Such a distribution of control functionalities requires a corresponding device on the customer side that performs or mediates between the energy grid requirements and the customer...
