The conventional distribution networks are designed for mitigating the voltage drop and unbalance problems at peak times through voltage regulation by using shunt capacitors. With the integration of photovoltaic (PV) units in these networks, the voltage rise at off-peak period is considered as growing concerns. This paper proposes a dump load as an added low-cost voltage regulator in the distribution network to moderate voltage rise and unbalance problems in distribution networks. The performance of the proposed method is compared with that of a distributed static synchronous compensator (dSTATCOM) by finding the optimal location and size of voltage regulators in the distribution network for both off-peak and peak load conditions. The designed voltage regulators consist of capacitors, dump loads and a dSTATCOM. A case study and numerical results are considered and compared in term of voltage unbalance factor, the voltage deviation, and power losses.

Voltage and current unbalance are common power quality problems in power grids. The penetration of single phase inverter interface photovoltaic panels will impact the voltage profile and voltage unbalance index of Low and Medium voltage distribution network. Due to lack of sufficient monitoring point in the distribution network, an assessment method of evaluating the voltage unbalance index is of paramount importance. Due to stochastic nature of the location and rating of photovoltaic panels, a probabilistic method based on Monte Carlo simulation is proposed to assess the voltage unbalance factor. The simulation is run using MATLAB and PowerFactory, based on proposed data exchange between the two software packages. The effect of the timing mismatch between solar generation and load profile is also studied using a time sweep simulation. The result of simulation shows that there is a low probability that the penetration of photovoltaic panels render the voltage unbalance factor to exceed the limits. However, the variation of solar generation and loads during the day might be of concern, especially during low demands periods.

In this paper, the feeder voltage regulation problem of low-voltage distribution network due to high penetration of solar PVs has been addressed. This paper proposes and evaluates the performance of an event-triggered distributed voltage control strategy to regulate the bus voltages within allowable limit in a domestic low-voltage redial feeder. A leader-following distributed control strategy has been proposed to control the bus voltages through the feeder, which is robust to any bus voltage order. This leader-following distributed control requires communicating only with immediate adjacent buses to implement the distributed voltage control. An event-triggered communication scheme has been introduced for the data transmission between adjacent battery energy storage systems (BESSs) to reduce the amount of communication. The performance of the proposed controller has been evaluated in a realistic radial distribution feeder in MATLAB/ Simulink environment.

The deployment of Solar Photovoltaic Systems (SPS) is now a predominant activity to achieve the large-scale penetration of Renewable Energy Sources (RES) for access to low cost electric power, both for urban and rural India. In this backdrop an user friendly, reliable and modestly priced PV characterization technique is imperative. This is highly required for the PV industry and also by the consumers and researchers in this area. Thereafter, the reliability analysis of the essential parameters of Poly-Si Solar PV modules during the early monsoon has been initiated in this work. The impacts of clearness index (KT) on the performance parameters have been critically examined. Studies show that, even during the monsoon in this tropical zone, the Poly-Si modules maintain a steady performance with respect to their estimated electrical parameters. Work is currently in progress to extend the deployment of this new metrological practice to available modules of higher wattages in various other seasons.

A method of frequency response analysis (FRA) is broadly used to observe a deformation of power transformers. The transmitting and receiving windings in magnetically coupled wireless power transfer (WPT) system can be considered as an air core transformer. This paper presents a new application of FRA with the circuit analysis, finite element method (FEM) simulations and the practical analyses on the prototype of two-winding WPT system that operates at the resonance frequency of 1.16 MHz. The FRA results contribute to a verification of the power transfer coefficient over the distance and to an enhancement of the transfer efficiency of WPT system. In addition, the critical distance occurring the maximum power transfer and the decline of the efficiency due to the frequency bifurcation at the near gap between the windings can be analyzed.

Now more than ever, renewable energy technologies have become a key player in improving accessibility to energy on the African continent. Focusing on the developing nation of South Africa, published works have indicated approximately thirteen criteria for selecting renewable energy technologies. Consideration was given to developed criteria and how they were used from technical, economic, social, environmental and political stances. The aid of analytical hierarchy process (AHP) and an established decision-model the author endeavored to substantiate a method of selecting appropriate technologies. These technologies were ranked in order of priority using South African energy projects. Case study information for onshore wind, solar photo-voltaic, concentrated solar thermal, biomass and small hydro energy alternatives were used to apply the decision-model for their ranking and prioritizing. The overall outcome of the decision-model identified that solar energy is the most suitable for South Africa and should be developed for long-term policy and energy roadmaps.

The deployment of energy storage for long/medium term has become a major challenge in electrical systems. Investigation of various components of traditional Daniell electro-chemical cell and implementing new materials such as Kevlar carbon fiber electrodes and a porous membrane as the separator rechargeable characteristics to create a modified rechargeable Zn-Cu cell was achieved. As a proof of concept, a 3D printed micro-cell was constructed for testing and charging As the research uses aqueous electrolytes, future modifications and research in cell construction can also be used to construct a a potential Zn-Cu redox flow battery, which would then have the potential to store energy over long periods in copper sulphate solution and zinc metal. This could provide a useful alternative energy storage for isolated renewable resource PV based micro-grids in many parts of the world.

With the increasing use of renewable energies around the world, particularly photovoltaic (PV) systems, considerable research efforts have been dedicated to achieving maximum efficiency. Maximum Power Point Tracking (MPPT) techniques are proposed for PV systems to increase the energy capture. The type of MPPT method utilized in a system can directly influence the energy capture positively, however may also have an unwanted side effect in causing voltage stresses in the converter components which may effect the overall reliability of the system. This paper provides a preliminary investigation of the impact of the choice of MPPT method on the voltage fluctuations in the DC-link and PV-side capacitor of a PV system. The investigation is a first step in working towards a method for assessing the impact of the choice of MPPT method on the reliability of the converter.

This paper proposes a bi-level transactive market clearing model with a coordinated integration of large-scale renewable and end-users' demand response (DR) capable loads. The model involves two levels hierarchical decision. In upper-level, responsive load scheduling problem to minimize demand response (DR) compensation cost is solved for DR aggregator. The lower-level deals priority order dispatch of generation resources including a solar PV farm (PVF) while considering the committed DR in upper-level to minimize day-ahead operation cost. Mixed integer linear programming (MILP) is used to solve aggregator's problem in upper-level and security constrained optimal power flow (OPF) is used for the later. Supply offer price of PVF is captured by a probability density function. Storage units are considered to backup farm's dispatch capability beyond of peak sun hours (PSH) and assume to be getting charged by its surplus energy. The model has been verified using a sample 6-bus power system with several case studies to demonstrate benefits of large-scale PV and DR aggregation.

This paper explores the collection efficiency of Electrostatic precipitator (ESP) of a laboratory scale model which is geometrically similar to the industrial ESP of a local coal based power station. The variable fly ash velocity is used to determine the collection efficiency of an ESP. The applied voltage and current are being kept constant during different field test. Moreover a test run will be conduct to see the collection efficiency without applying high voltage. The experimental result shows that ESP collection efficiency is higher at lower fly ash velocity and suddenly decreases after a range of velocity. To confirm the validity of collection efficiency a mathematical model has been built and verified with experimental data. In addition, a test run is conducted without the high voltage (HV) supply to see the ability of capturing fly ash particles by keeping all other parameter same. The peak efficiency of ESP found in this experiment is 99.87%.
