This paper introduces a new fault location algorithm(FLA) for three-terminal transmission lines using positive sequence components of currents and voltages available at all three terminals. The proposed fault location algorithm simultaneously able to identify the faulted section and hence estimates the location of the fault. For various fault types and fault resistance values, simulation tests have been carried using PSCAD for a 161kV power system network. And later the algorithm is implemented in MATLAB. The proposed algorithm is tested for estimation of the fault location for different fault types with various fault resistances. It can be observed from the results,that for 99% of the cases tested, the % error is less than 1%.

Microgrids (MGs) provide solutions to various problems in power systems by integrating non-renewable and renewable energy sources like combined heat and power (CHP) plants and distributed energy resources (DER). This paper has developed an optimization framework for economic dispatch of microgrids, including heat storage tanks and to increase the flexibility of CHP plants and boiler units. In addition, conventional power generators, intermittent energy resources such as photovoltaic (PV) units, wind turbines and battery energy storage system (BESS) are modelled in a modified IEEE 33 bus test system MG operating in islanded mode. Local generation and DER penetration can help system operators to satisfy energy demands with no need to purchase power from the grid. The main goal of the proposed paper is to optimally and economically dispatch heat and electricity considering impacts of heat buffer tank and battery energy storage, taking into account the technical constraints like AC/DC power flow limitations and the effects of dual dependency of produced heat and power by CHP units. The MG is studied within a time horizon of 24 hours and obtained results are analyzed for comparison.

The integration of intermittent renewable energy sources (RES) would challenge system operators to ensure the required system inertia (SI) and primary frequency response (PFR). The decline in response would arise system security and reliability concerns due to post fault frequency dynamics during contingency like the largest generation or load loss. These challenges can be addressed through incorporation of additional resources of frequency response in the system. Battery Energy Storage Systems (BESS) due to its high power density and fast response is a viable alternative to maintain post-fault system dynamics, and thus maintain system security. In this context, the paper investigates the BESS potential for PFR adequacy in a day- ahead security-constrained generator scheduling problem under different RES integration. Further, a sensitivity analysis of BESS for PFR adequacy is presented. Frequency security parameters like SI, nadir-frequency are examined under the largest generator outage for the analysis. Simulations are performed on a New-England 39 bus test system to demonstrate the efficacy of the proposed model.

This paper aims at development of the automated load control potential of buildings through control of heating, ventilation and air-conditioning (HVAC) system to provide ancillary services to the grid. The power consumption of HVAC is optimized in response to the reference signals while ensuring maximum thermal comfort. Accordingly, a coordinated control strategy is developed to control the HVAC power consumption and charging/discharging cycles of energy storage. By variation of the set temperature within a user defined bandwidth, the HVAC is controlled to provide ancillary service to the grid. Similarly, battery energy storage system is controlled to respond to ancillary service request during limited HVAC control owing to user comfort satisfaction. Results reveal that proposed strategy for power sharing and coordinated load control is able to robustly mitigate power mismatches.

This paper proposes a HC-LMS (Hyperbolic Cosine function Least Mean Square) based control technique for a double stage grid-connected solar photovoltaic array (SPVA) system. This control technique has less oscillations and swift dynamic response. This HC-LMS control technique extracts the harmonics free fundamental load current component for the switching of DC-AC converter. Moreover, it addresses various PQ (Power Quality) problems like harmonics mitigation, grid currents balancing and reactive power compensation. For efficient operation of solar PV array, an IC (Incremental Conductance) based MPPT (Maximum Power Point Tracking) technique is used to achieve crest power. This HC-LMS control technique is tested under different dynamic conditions in the laboratory and test results show the satisfactory responses. The THDs (Total Harmonic Distortions) of grid currents are achieved well within the recommended limits.

Increasing penetration of electric vehicles (EVs) in distribution system may result in increased losses and voltage drop in distribution system due to their charging load. However, EVs can also act as mobile energy and power resource to the grid. The concept is known as vehicle to grid (V2G) operation of EVs. EVs can dispatch real and reactive power to the grid through V2G provision to support the operation of distribution system. In this study, scheduling strategy of EVs is implemented considering real power dispatch and reactive power dispatch from the EVs. In addition, distribution system reconfiguration (DFR) is utilized to optimally coordinate the V2G provision available from EVs. The proposed optimization is solved using Grey wolf optimization (GWO). Constructive influence of DFR is evaluated on 69-bus radial distribution system with different cases. It is shown that DFR plays a significant role in enhancing the operation of distribution system integrated with EVs.

In this paper, a non-isolated dc-dc converter is proposed to provide a high voltage gain with a low inductance requirement. The circuit can be generalized for multiple stages to realize the desired DC output voltage from a low DC voltage source. In the proposed topology, the capacitors and inductors are charged/magnetized in parallel and discharged/demagnetized in series during switched on and off period respectively to obtain a high step-up voltage gain. The proposed power circuit is suitable for many applications based on renewable energy and energy storage where the desired DC-link voltage requirement can be as high as 560V (three-phase inverter input), and input voltage can be as low as 48V (a string of four batteries or fuel cell). A detailed analysis of the steady-state operation of the power converter is provided in this paper to obtain the voltage gain of the converter. The circuit design is simulated in MATLAB Simulink to verify the results of the analysis of this converter. Further, the design guidelines are provided for the generalized form of the converter to achieve desired steady-state input-output gain.

This paper presents a research work focussed on the identification of faults on the distribution feeder supported by Stockwell transform based summing of absolute values and median features using the voltage signals. A fault index is proposed which is obtained by the multiplication of H-index (obtained summation of absolute values S-matrix evaluated by ST supported decomposition of voltage) and VS-index (obtained median of absolute values S-matrix evaluated by ST supported decomposition of voltage). Classification of faults is achieved using decision rules. Investigated faults include phase to ground, fault between two phases, two phases to ground fault and fault involving all three phases and ground. Performance of algorithm is tested on high fault impedance and fault incidence angle. Proposed study is performed using MATLAB software in Simulink environment.

Remote monitoring of electrical equipment in the existing power system network has become indispensable for ensuring the reliability and efficiency of entire power network. This paper presents a robust wavelet domain based image processing technique for deblurring aerial images of suspension type insulators to be employed in the power transmission network. The proposed technique modifies the wavelet transform coefficients of blurred aerial images. The resultant deblurred images, though, have small artifacts near edges but they do not cause any loss of significant information. The key contribution of this paper is validation of proposed algorithm on Xilinx ZedBoard to test the robustness of proposed technique for real-time applications.

Fluctuation of voltage in the low power distribution grid, to which distributed energy resources (DER) are integrated, is a major power quality (PQ) concern. Particularly when the generation from the DERs is at the peak value of it and load requirement is minimum and either case also. In such cases, many PQ problems emerge at the point of common coupling (PCC) such as voltage sag, voltage swell and harmonics. Due to such problem supply to the load, become discontinuous i.e. unregulated supply to load. Therefore, it is indispensable to regulate the voltage of PCC. This paper presents a method to regulate the PCC voltage by connecting the renewable energy sources (RESs) with an R-C filter to the grid. This filter thus lessens the harmonics to a level as stated in the IEEE standard 519. The comparative analysis is done between the solar energy source with and without maximum power tracking to check their compatibility to integrate them with the grid. The autonomous power management (APM) system along with THD reduction is considered to reduce the power losses during islanding mode. The analysis of the solar model with and without maximum power is simulated in MATLAB software and the results of the simulated model are presented to endorse the effectiveness of this structure.
