Nov 1, 2019 publication description7th International Conference 2019 – University of Sabaragamuwa Sri Lanka
Currently, enormous electrical energy is wasted by the street lighting systems. In Sri Lanka, there exist several types of street lighting systems. There are switches fixed to the street light poles that are situated along the roads, usually people neglect to switch off and wasting energy during the day. A set of street lights with a single switch to turn on and off is another type and this systems requires additional wiring for controlling. The street lights that connected to a photodiode which operates according to the sun light level another type of street lighting and that cannot be operated remotely as it automatically turn the lights on and off. Thus, a massive amount of energy is wasted. The street light system of wireless operated also not suitable for street lights in countries such as ours, because the wireless automation unit cost is high. This problem leads to the necessity of a smart control system for street lighting in Sri Lanka. In this research, a low cost automated control system for the street lights is proposed and that will reduce the power wastage and increase the efficiency. By using the planned system, each and every light can be controlled whenever needed, without additional cost for wiring to control the lights and switches for each and every pole. For the experiment, the X-10 protocol has been selected as the power line communication protocol which had been using for the automation of home electrical systems. With the proposed system, control signal can be sent over the power lines instead of the requirement of wiring another line for controlling is advantageous than wired and wireless systems. Fixing the implemented receiver unit for each and every light is sufficient. The cost of receiver unit also will be less comparing to the existing systems and cost of energy wastage.

Design and Analysis of PID and Fuzzy-PID Controller for Voltage Control of DC...Francisco Gonzalez-Longatt
DC microgrids are desired to provide the electricity for the remote areas which are far from the main grid. The microgrid creates the open horizontal environment to interconnect the distributed generation especially photovoltaic (PV). The stochastic nature of the PV output power introduces the large fluctuations of the power and voltage in the microgrid and forced to introduce the controller for voltage stability. There are many control strategies to control the voltage of a DC microgrid in the literature. In this paper the proportional-integral-derivative (PID) and fuzzy logic PID (FL-PID) controller has been designed and compared in term of performance. Performance measures like maximum overshoot and settling time of FL-PID compared with the PID proved that the former is better controller. The controllers are designed and simulated in the MATLAB programming environment. The controllers has been tested for the real time data obtained from Pecan Street Project, University of Texas at Austin USA.
PHOTOVOLTAIC MANAGEMENT SYSTEM USING POWER LINE COMMUNICATION METHODOLOGYEditor IJMTER
Energy consumption in residential areas is rising; residential areas have deployed a
photovoltaic (PV) system to save energy cost and provide continuous power in the area. The PV
system needs to be continuously monitored to maintain its performance. In addition, it is desirable to
monitor each PV module because one abnormal PV module affects the whole PV system. Here
Power line communication (PLCC) technology is used to monitor each PV module in order to check
the performance of PV system. Power line communication (PLCC) carries data on a conductor that is
also used simultaneously for AC electric power transmission. The parameters in PV module are
monitored by PLC. The system architecture is composed of the following components: PLC modem,
CUK Converter, and inverter connected with AC load. The PLC modems are deployed on each PV
module for continuous monitoring. The CUK converter will provide constant voltage to the battery.

photovoltaic module.Voltage, Current and Temperature are the parameters which are going to be
noted in PV module. The output of the inverter circuit is given to the AC load by using resistive load.

The establishment of the latest IoT systems available today such as smart cities, smart buildings, and smart homes and wireless sensor networks (WSNs) are let the main design restriction on the inadequate supply of battery power. Hence proposing a solar-based photovoltaic (PV) system which is designed DC-DC buck-boost converter with an improved modular maximum power point tracking (MPPT) algorithm. The output voltage depends on the inductor, capacitor values, metal oxide semiconductor field effect transistor (MOSFET) switching frequency, and duty cycle. This paper focuses on the design and simulation of min ripple current/voltage and improved efficiency at PV array output, to store DC power. The stored DC power will be used for smart IoT systems. From the simulation results, the current ripples are observed to be minimized from 0.062 A to 0.02 A maintaining the duty cycle at 61.09 for switching frequencies ranges from 300 kHz to 10 MHz at the input voltage 48 V and the output voltage in buck mode 24 V, boost mode 100 V by maintaining constant 99.7 efficiencies. The improvised approach is compared to various existed techniques. It is noticed that the results are more useful for the self-powered Embedded & Internet of Things systems.
Several algorithms have been offered to track the Maximum Power Point when we have one maximum power point. Moreover, fuzzy control and neural was utilized to track the Maximum Power Point when we have multi-peaks power points. In this paper, we will propose an improved Maximum Power Point tracking method for the photovoltaic system utilizing a modified PSO algorithm. The main advantage of the method is the decreasing of the steady state oscillation (to practically zero) once the Maximum Power Point is located. moreover, the proposed method has the ability to track the Maximum Power Point for the extreme environmental condition that cause the presence of maximum multi-power points, for example, partial shading condition and large fluctuations of insolation. To evaluate the effectiveness of the proposed method, MATLAB simulations are carried out under very challenging circumstance, namely step changes in irradiance, step changes in load, and partial shading of the Photovoltaic array. Finally, its performance is compared with the perturbation and observation” and fuzzy logic results for the single peak, and the neural-fuzzy control results for the multi-peaks.

Many wireless sensor network (WSN) applications, nowadays, require real-time communication, which demands cautious design consideration to resolve inherent conflicts between energy efficiency and the need to meet Quality of Services (QoS), such as end-to-end delay communications. Numerous innovative solutions are proposed such as Real-time Power-Aware Routing (RPAR) protocol, which dynamically adapts transmission power to meet specified communication delays at low energy cost. Hence, to enable real-time communication with RPAR protocol, an adaptive Power Management Circuit (PMC) using hybrid energy harvester to support WSN real-time communication is proposed. In this paper, a high-level architecture of the proposed PMC is discussed, which consists of Thermal Energy Generator (TEG), and Piezoelectric Energy Harvester (PEG) as energy providers, with low-power Maximum Power Point Tracking (MPPT) feature enabled. Preliminary simulations which analyze and characterize TEG and PEG system are conducted separately to determine the optimal design parameters to support the conventional WSN QoS requirement. Next, both systems will be integrated into a single PMC implementation prior to fabrication and lab characterization.

Optimized energy efficient lighting system for green buildingseSAT Journals
Abstract
Increasing population places increasing demands on energy supply, which leads to heavy power deficiency. We can supply only a
limited amount of energy to the consumers because we have only limited conventional sources of energy and non-conventional
energy sources are mostly still under research and have not been deployed on a large scale. Not only there is limited amount of
energy to be supplied to the consumers but heavy demand of energy supply also leads to environment degradation. This creates a
need to use the limited energy efficiently. This has given rise to new trend towards reducing the energy consumption: Green
Buildings. About 40% of the energy consumption in the world is consumed by buildings [1]. Energy consumed by lighting systems
accounts for about 15% of total energy consumption of buildings [1]. Thus we need to use energy efficient lighting devices for
illuminating buildings. Thus in this study we to tend to develop optimized energy efficient system, which will use LED lights to
illuminate buildings. The illumination intensity of the LED lights will be decided by the FPGA, which is interfaced to the LED
driver. Based on combined values of light intensity of the room and occupancy of the room using different sensors, the light output
of the LED will be controlled.
Keywords: LED Lighting System, FPGA, Green Buildings, Auto-dimming.
This paper discusses the principle of operation, dynamic modeling, and control design for light-to-light

this paper is composed by a photo- voltaic (PV) panel, an LED array, a dc–dc converter dedicated to the
maximum power point tracking of the PV panel and a dc–dc converter dedicated to drive the LEDs array. A
system controller is also included, whose goal is to ensure the matching between the maximum available PV
power and the LED power by means of a low-frequency LEDs dimming. An experimental design example is
discussed to illustrate the functionalities of the LtL system.

Development of Fuzzy Logic Control for Indoor Lighting Using LEDs GroupTELKOMNIKA JOURNAL
This paper presents the design and the development of an indoor lighting control based on fuzzy
logic controller (FLC). The objective of this study is to demonstrate how the FLC can optimize the lighting
based on indoor and outdoor lighting environments. The FLC system uses two inputs with Light Dependent
Resistors (LDR) as a sensor at indoor and outdoor lighting environments. The output is Light Emitting
Diodes (LEDs) to provide lighting at the room automatically. The Pulse Width Modulation (PWM) is used to
adjust the LEDs lighting in the room. FLC has successfully demonstrated performance to control the output
of LEDs as needed. If the LDR 1 input as indoor sensor shows dim, it will automatically turn on brightly.
The MSE values for simulation and experiment of LDR 1 and LDR 2 were 34.42 and 30.11 respectively.
The results of FLC performance in the simulation work are further validated by an experimental work.
Experimental results show similarities compared to the simulation results.
With the rise of containerization, as well as the established adoption of virtualization technologies, run-time power and energy management is becoming one of the key challenges in modern cloud computing. This is also fundamental as power consumption contributes to the 20% of the Total Cost of Ownership of a datacenter and energy costs will exceed hardware costs in the near future. In this context, several goals towards power optimization can be achieved. On the one hand, power capping can be enforced and on top of that the system should be able to maximize performance. On the other hand, when performance are critical, the system should be able to provide a minimum SLA and optimize power consumption without violating it. Within this context, we propose a common autonomic methodology based on the ODA control loop for containers and virtual machines. The proposed methodology is able to achieve 25% power savings for containers and can improve performance under a power cap for virtual machines.
The high power consumption of conventional street lighting systems, and the consequences on environmental ecosystem due to continuous turning ON of light, have led researchers to seek solutions to this problem. LED light dimming system has been presented in many studies using computerized systems with or without wireless monitoring facility. The demerits of these systems include complexity, high cost and unfixed data transfer speed. This paper proposes to reduce power consumption of street lighting through a decentralized light dimming system that is based on Pulse Width Modulation (PWM). This is in addition to replacing conventional high power lamps with lower power LED lamps. The dimming control circuit of this system is fixed on each pole and controlled individually resulting in faster and more reliable response. The proposed system uses the available infrastructure and is suitable for small or main streets regardless of the number of light poles. It is also flexible in its coverage distance due to the freedom of motion detector selection. The advantages of using LED lighting on the environment as compared to conventional lighting are explained. Simulations reveal the effectiveness of the proposed system on energy saving and on the environment.

Cracking the Workplace Discipline Code Main.pptxWorkforce Group
Cultivating and maintaining discipline within teams is a critical differentiator for successful organisations.
Forward-thinking leaders and business managers understand the impact that discipline has on organisational success. A disciplined workforce operates with clarity, focus, and a shared understanding of expectations, ultimately driving better results, optimising productivity, and facilitating seamless collaboration.
Although discipline is not a one-size-fits-all approach, it can help create a work environment that encourages personal growth and accountability rather than solely relying on punitive measures.
In this deck, you will learn the significance of workplace discipline for organisational success. You’ll also learn
• Four (4) workplace discipline methods you should consider
• The best and most practical approach to implementing workplace discipline.

Box 513, 5600 MB, Eindhoven, The Netherlands Aly.Syed@NXP.com, {s.bhardwaj, t.ozcelebi, j.j.lukkien}@tue.nl, Introduction Energy is becoming expensive and electricity providers are coming with different schemes for billing. One model is that a building gets a quota of electric power that it is allowed to use. If the building uses more power than its quota, then a significantly higher price for electricity is charged. This way, electric energy providers can plan their power generation in a cost effective manner. A building is assigned a power usage quota. This building has two types of rooms, rooms that have a high priority and rooms that have low priority. The high priority rooms are allowed to use the power according to whatever demand there is at a time, while the low priority rooms are obliged to use the power that is leftover from the quota after the consumption of high priority rooms has been subtracted. The system in this building takes power consumption in the high priority rooms and adjusts the lighting in the low priority rooms such that the quota assigned to the building is maintained. Use Case Scenario Semantic Interoperability ,[object Object],[object Object],[object Object],[object Object],[object Object],Conclusions Objective The major goal of this system is to demonstrate interoperability between two sub systems namely OSAS (TU/e-SAN) and NXP lighting system which are based on different architectures using SOFIA Smart M3 approach. System Architecture We developed a power-managed smart LED lighting system composed of various types of embedded devices with different computing and communication platforms, forming a heterogeneous network. The power management information is exchanged between different networks and devices using an ontology-based semantic interoperability architecture, namely Smart-M3. The proposed priority mechanism ensures accurate maintenance of the overall power consumption levels, always keeping it under a given power quota for the building. This behavior is regardless of changing external lighting conditions as the smart lighting system introduced is capable of adjusting light output levels from individual luminaries as well as their power consumption in both LoPR and HiPR.
