Power quality and load management are being considered as two most important features of the recent hybrid micro parks. In this paper, a control and effective management philosophy has been proposed for hybrid micro parks. The renewable energy resources such as solar PV, wind energy conversion system along with energy storage have been integrated to the individual DC links and consequently, these independent DC micro parks are being interconnected to the common AC link via tightly regulated power electronics interfaces. The AC link interfacing converters transfer the real power from the renewable energy resources along with power quality enhanced features. An integrated boost DC-DC high gain power converter has been used as a solar peak power point tracker and on the other hand, a fully controlled AC-DC converter have been utilized as a wind peak point tracker from the permanent magnet synchronous generator (PMSG) based wind energy conversion system. Energy time shifting and power flow management are the key features being provided by the energy storage system. The effectiveness of the proposed coordinated methodology for aforementioned hybrid micro parks has been verified by the detailed digital simulation studies.

Schemes adopted for protection of busbar face major challenges in terms of speed, sensitivity, and immunity against current transformer (CT) saturation. This paper reports a new busbar protection scheme using Bayes Point Machine (BPM). A substation model with double bus configuration has been simulated in PSCAD and one cycle post-fault current samples are utilized to identify the fault zone. The proposed algorithm has been tested for diversified fault scenarios including the cases for which the conventional line differential protection scheme (87L) is likely to maloperate. BPM is found to be more than 99% accurate while identifying the correct fault zone. A comparative evaluation suggests the superiority of BPM among other machine learning based classifiers.

The main objective of constructing a Small Hydro Power Plant (SHPP) is to generate electric power while facilitating water supply to irrigation fields or drinking from a storage dam or run of river scheme. But hydropower plant is usually built with the consideration of past hydrological regimes and do not take climate change into account during its planning stage. Therefore, selection of hydro generating units with the modern technology and the consideration of climate change are essential to allow SHPP for the sustained operation. This paper presents the techno-economic evaluation of fixed and Variable Speed Technology (VST) in a 4 MW SHPP, proposed in Erach dam (India). Selection of hydrogenating units, with minimum installation cost, in consideration of climate change is the main focus of present work. Turbine speed is adjusted in accordance with the water discharge to maintain good efficiency at partial generation. Power Electronic Converter (PEC) is connected in stator circuit of synchronous generator to meet the grid requirements. This study reveals that VST helps in reduction of number of hydro generating units to achieve the targeted energy generation which leads to significant reduction of installation cost and increase the sustainability of plant at changing climatic conditions.

Very fast transient overvoltages (VFTO) generated in a gas insulated substation (GIS) during disconnector switching operations is one of the major concerns in insulation design of the GIS. Such over voltages can cause malfunctioning of the protection and control circuits in addition to initiating faults inside the gas insulated bus ducts of the substation especially in the presence of metallic particles. In this paper, VFTO have been estimated at various points in a 1000 kV rated substation for all possible valid disconnector switching operations. For the substation studied, the maximum computed overvoltage is 1.58 pu without considering the trapped charge on the busbar. Major frequency components in the simulated VFTO lies in the range of 840 KHz to 30 MHz. Simulations have been carried out using the Electromagnetic Transient Program (EMTP).

In this paper, a strategy for home appliances management is proposed in order to provide incentives for consumers of the residential sector to defer their electricity use and to reduce consequently their energy consumption and their contract power. The mathematical model formulation is based on a problem-solving approach with predefined constraints. The proposed algorithm is then applied to different types of loads, according to various appliances criteria like flexibility, interruptibility, shiftability, involving a control scheme suited to each appliance feature. An example of application is finally detailed to illustrate the consistency of the proposed management process. Different scenarios of constraints are then proposed and analyzed. The response of the control scheme is subsequently presented and argued and the results confirm a good agreement with the objectives of the load scheduling, which validates the proposed management strategy when subjected to specific constraints.

This paper presents three-phase interleaved inverter topology to enhance the operation of shunt active power filter (SAPF) for mitigating current harmonics, reactive power, shoot-through problem, etc. Conventional voltage source inverter (VSI) has failure mode of operation which causes to damage the power switches. This proposed interleaved inverter avoid conduction through same leg switches. Therefore, no shoot-through mode in the circuit operation of the interleaved SAPF. The proposed interleaved SAPF uses a modified indirect current control technique for generating distorted free reference current. Therefore, switching notches and ripples have been eliminated in the source current which improves the source current %THD. The performance of proposed interleaved SAPF and control algorithm has been designed and tested in MATLAB/ Simulink environment. The proposed interleaved SAPF with proposed control algorithm is effectively mitigating current harmonics, reactive power for unity power factor operation and removes the notches in the source current without shoot-through problems. The complete simulation results have been presented.

DC grids are becoming popular due to higher efficiency and simple solar integration architecture. DC grids enable implementation of simple structures like compact linear LED drivers. But due to variations in LED characteristics from one batch to another batch (variation in manufacturing process) and use of dimming to control light output, implementation of compact linear LED drivers results in loss of efficiency. To overcome the problem of variations in LED voltage, cumbersome binning process may be employed. But with aging or/and temperature variation, this implementation does not result in satisfactory solution. In the proposed model, low cost small compact boost converter is serially connected with analog modulated/unmodulated linear LED driver. In the proposed driver, mini-boost driver of one-tenth capacity is employed in series with linear driver for providing variable constant current to facilitate wide dimming range.
