Frequency regulation in MG using conventional PID controllers becomes more challenging in the presence of stochastic load and uncertainty in system parameters caused by dynamic perturbation. So, there is a need for a robust controller with acceptable performance and stability for regulating the frequency in MG. The dynamic perturbations include changes in inertia constant and damping coefficient of the power system, which directly affect the frequency of the MG. In this paper, structured Hm synthesis has been done for robust frequency control in islanded MG. The sources used in MG for compensating the load demand are fuel cell, diesel engine generator and microturbine. The robustness and performance of Hm based controller is validated in the presence of parametric uncertainty and load disturbance caused by stochastic nature of load. The synthesized Hm based controller is tested for robust stability and performance against ± 50% perturbation of inertia constant and damping coefficient of power system. Simulation results of complete system is also validated with hardware using dSPACE 1104 and control desk.

With technology evolving at a drastic rate, our lives have been integrated with them. Countries have taken a step into a new era of Smart Cities enabling technology to increase the quality of life. This project delves into the study ad understanding of the Internet of Things (IoT) concept and how it plays a part in Singapore's Smart Nation initiative, specifically in a Smart Home. A Smart Home prototype model was build using two Arduino boards and incorporates various sensors such as a lux sensor, a temperature and humidity sensor and a PIR motion sensor. These sensors allow several devices that are connected in the model to function according to external inputs from the environment to decrease the total energy consumption. Coupled with these sensors, are a pair of Xbee modules to transmit a desired power value keyed in via a keypad between the Arduino boards to limit the total energy in of the devices in the model. A simulation model of a Smart Home network was also created using Cooja simulator running on Ubuntu to better facilitate the understanding of the IoT. It portrays four Tmote sensors that is connected to an Area Border Router (ABR) using the RPL protocol. This connection gives an external IPv6 value to the sensor nodes allowing their data to be access through the border router.

This paper proposes a two-stage residential demand response (DR) framework for smart community to coordinate the benefits of households and transformer aging. In the first stage, the loss of life (LOL) cost of the transformer is used to quantitatively describe transformer aging and is formulated into the DR cost model, then an aggregator optimization is formed to determine the optimum amount of transformer load deferment and curtailment. The second stage in terms of maximizing the community benefit from DR is used to optimally schedule the transformer load from the aggregator to each individual household. Case studies are presented to demonstrate the effectiveness of the proposed two-stage residential DR framework in the reduction of transformer peak load and improvement of household benefits.

This paper presents the state of the art closed-loop control technique namely the Field Oriented Control (FOC) for a Permanent Magnet Synchronous Motor (PMSM) drive. An effective model implementing FOC with field-weakening control is presented to analyze and control the performance of a PMSM drive over a wide range of speeds including the constant torque and constant power regions of operation. A sinusoidal pulse width modulated (SPWM) three-phase voltage source inverter (VSI) fed low-power surface-mounted PMSM (SMPMSM) drive system is modeled and simulated in MATLAB/Simulink environment. It is analyzed for various dynamic operating conditions for speeds ranging from as low as 100 rpm to 3500 rpm. The maximum speed attainable in field-weakening region is found to be dependent on the machine parameters. This is further validated by the simulation results of the drive under investigation.

This paper proposes a novel modulation strategy for active rectification of a single stage, isolated, three-phase high frequency link DC-AC converter. The proposed modulation strategy results in zero voltage switching (ZVS) of the DC side converter and zero current switching (ZCS) of AC side converter at all operating conditions without using additional snubber circuit. The technique also ensures magnetic flux balance of transformer within a switching cycle. High frequency transformer (HFT) flux balance results in significant reduction in size and weight and hence improves power density. The paper presents a detailed description of the proposed modulation strategy for unity power factor (UPF) operation. Important simulation results are shown to verify the converter operation.

This paper proposes an optimization methodology to estimate the parameters of multilayer earth structure by using the hybrid genetic algorithm and particle swarm optimization. By using four wire Wenner method on the ground is to acquire the experimental apparent resistivity curve. With the measured experimental apparent resistivity, can compute the theoretical apparent resistivity curve and estimate the soil parameters such as a number of layers, thickness of each layer (Nth layer thickness is infinity) and its resistivity. The representation of unknown soil is determined by comparing the closeness of experimental apparent resistivity curve with the theoretical optimized apparent resistivity.

In this paper, a novel HVDC system is proposed for using Shunt Capacitance Commutated Converter (SCCC), and analysis of work and wiring method are given. The basic idea of the SCCC is connect the capacitors in parallel between the converter transformers and the converters at the valve winding. The parallel capacitor is used to compensate for the vast majority of the inductive reactive power which can be required during the operation time. It is proved that the SCCC not only has the advantages of reducing the failure chance in commutation of the inverter, but also can makes the capacity of the converter transformer be utilized fully. The 500 kV HVDC monopole operation system about Huizhou City, Guangdong Province Echeng as an example, conducted by simulation of the system software (MATLAB). Gotting the AC side voltage and current waveforms and the DC side voltage and current waveforms during the operation of the SCCC. It is shown that the SCCC can not only overcomes the inherent defects of the traditional HVDC converter, but also can optimizes the operation state of the converter transformer and the whole systems.

The use of Self excited induction generators (SEIGs) often suffers from a common pessimistic reason of poor voltage regulation, which rules out the scope for utilizing the characteristic advantages of the machine in far flung areas. But with the advent of power electronic devices the generated voltage can be effectively controlled. Previous conventional strategy to control the voltage was by means of utilizing back to back converters. But this method suffers from the disadvantage of complex circuitry and increased cost. A cost effective control method has been studied for voltage control of dual SEIGs for low power generation in small industries and rural areas. SEIGs are taken in consideration because of their high availability in rural areas. The effects of various parameters are observed on the overall system. The method has advantages over the conventional method in terms of cost and easy controllability.

This paper aims to analyze the impact of communication delays on the performance of Plug-in electric vehicles (PEVs) charging power control for frequency stabilization based on Wide-Area Monitoring and Control (WAMC). Phasor Measurement Unit (PMU) is utilized in data acquisition for achieving the input signal of PEVs charging power control. In practical integration aspect, the communication delays are assessed for obtaining the impact of the PEVs charging power control consisting of synchrophasor data gathering delay, synchrophasor data transmission delay, synchrophasor data aligning in Phasor Data Concentrator (PDC), application algorithm delay and control signal transmission delay from the control center to the local PEVs. The multi-area remote microgrid is performed and simulated using DIgSILENT Powerfactory simulation software. The PEVs charging power controllers are integrated at particular locations in the microgrid with different PEVs penetration levels. The multi-area remote microgrid is fully considered the dynamic behaviors in power system. Furthermore, Photovoltaic (PV) generations are integrated to consider the intermittent characteristic of renewable energy source (RES) using synthesized solar radiation. This paper also attains the dynamic of load characteristic according to consumers demand. The simulation study is analyzed with different communication delays for receiving the effect on the controller. Simulation results indicate the impact of some communication delays on each PEVs charging power control in the remote microgrid. The results also reveal the performance of the PEVs charging power control for stabilizing system frequency under the particular condition.

It is well known that proper reactive power reserve (RPR) is essential to avoid voltage instability and abnormal voltage. Most literatures limits the maximum supply of generator reactive power output by the maximum loading point. Thus the optimization of RPR usually involves two operating points, i.e. current operating point and maximum loading point. However, extreme differences exist between the statuses of generators at those two operating points and cannot be given in advance. That means current techniques cannot solve optimal RPR model directly. In this paper, a semi-definite programming (SDP) approach for solving optimal RPR model is proposed. Proposed method transforms the solution into iterations and each iteration is an optimal power flow problem solved by SDP. For demonstrating the validity of proposed method, IEEE 118 system in three load scenarios is set as the test case. The results prove the effectiveness and robustness of the proposed method.
