Introduction of dynamic pricing in present retail market, considerably affects customers with an increased cost of energy consumption. Therefore, customers are enforced to control their loads according to price variation. This paper proposes a new technique of Home Energy Management, which helps customers to minimize their cost of energy consumption by appropriately controlling their loads. Thermostatically...
The smart grid will increase building energy efficiency and conservation via combining information and communication technologies, advanced instrumentations, system intelligence, and information on the end user. Specifically Demand Side Management (DSM) programs serve as an aid in energy conservation and management strategies as well as in the collection of real-time consumption information data....
In this paper, a wireless sensor network based measurement system was proposed to conduct real-time measurement of energy consumption of household appliances and display this information on a graphical user interface on a computer. The system was also able to calculate an optimized schedule for the appliances to reduce energy cost in terms of time of use (TOU) tariffs. The sensor node and sink node...
In this paper, a novel platform is proposed for rapid prototyping and development of field-oriented control (FOC) based permanent magnet synchronous motor (PMSM) drives. A complete process, from model testing in the simulation stage to the actual hardware testing stage, is presented in detail. By using automatic code generation (ACG) through PSIM simulation blocks and a Hardware-in-the-loop (HIL)...
This paper presents real-time simulation results of a 512-level modular multilevel converter (MMC). Using off-the-shelf computers and FPGA boards, the converter, including the 6 valves, 6 arm inductors and the transformer, is simulated with a time-step of 450 ns. Such a small time-step is required to ensure high accuracy when applying gating signals but also when observing fault conditions. Simulation...
This paper introduces a novel QoS architecture for process automation. The proposed architecture leverages the concept of Software Defined Network. The architecture maintains the real-time communications based on the measured propagation time. It maintains the configurations by detecting and predicting the change of propagation time in addition to queue usage. The authors utilize the OpenFlow with...
In design of demand response programs, real-time pricing plays an important role. In real-time pricing systems, information of the price and power consumption is sent to an ISO (independent system operator) and consumers (i.e., smart meters) through communication networks. Hence, this system can be regarded as a class of networked control systems. In this paper, design of real-time pricing systems...
Real-time protocols originated from standard Ethernet technology have been gradually developed over the last decade. Candidates of real-time Ethernet protocols are EtherCAT and PROFINET IRT from Beckhoff and Siemens, respectively. In contrast to standard Ethernet, data-link layers of both Ethernet-like networks are modified from IEEE 802.3 in order to improve real-time capabilities for critical communications...
This paper presents methods and results for experimental performance assessment using Real-Time Hardware-in-the-Loop (RT-HIL) simulation of an Excitation Control System (ECS) for both terminal voltage regulation and power oscillation damping. The ECS configured for this study is Unitrol 1020 from ABB and its performance is assessed for both Automatic Voltage Regulator (Auto) and Field Current Regulator(Manual)modes...
Range anxiety is a major contributor in low penetration of electric vehicles into the transportation market. Although several methods have been developed to estimate the remaining charge of the battery, the remaining driving range is a parameter that is related to different standard, historical, and real-time data. Most of the existing range estimation approaches are established on an overly simplified...

A novel HIL bench with a cost-effective input and output interface between the control system under test and the real-time simulator is introduced. Two critical test cases, namely the start-up of the MMC connected to islanded...

Online condition monitoring is a crucial task for wind turbine generators availability and reliability enhancement and leads to an early electrical and mechanical faults detection which can reduce the maintenance cost and avoids catastrophic failures. The performance of any condition monitoring system should be evaluated before its installation on an actual full-scale system. Therefore, the design...
Building automation is a trusted technology to ensure user comfort in buildings. Today the challenge is not only to provide comfort, but to do it while having a close eye on the energy performance of the building. Distributed, renewable energy sources, advances in IT and tighter legislative constraints offer and demand changes in the way we operate buildings. We look at the core fields that enable...
In hybrid energy systems, batteries and supercapacitors are usually taken as storage mechanisms for smoothing output power, start-up transition, and various load conditions. As a result, developing hybrid power conversion systems has become an attractive research topic. In this study, a compact non-isolated bidirectional DC-DC converter is proposed to interface two DC power sources, which mainly benefit...
This paper presents a method to model three-phase saturable transformers for real-time simulation, using the example of a wye-delta configuration. The magnetizing path of the transformer is modelled with parallel connected linear inductors to simulate a piecewise linear saturation characteristic. Depending on the saturation state, the inductors are switched on and off via ideal switches, which are...
The use of real time digital simulation of large power systems is widely spreading due to its high precision result and increasing computing capability.

Most transmission utilities use dynamic studies...
Power hardware in loop (PHIL) is a simulation technique which allows testing of a power hardware under test (HUT) under various operating conditions.
