Service-oriented computing is a popular design methodology for large scale business computing systems. Grid computing enables the sharing of distributed computing and data resources such as processing, networking and storage capacity to Grid computing enables the sharing of distributed computing and data resources such as processing, networking and storage capacity to create a cohesive resource environment for executing distributed applications in service-oriented computing.

Grid computing represents more business-oriented orchestration of pretty homogeneous and powerful distributed computing resources to optimize the execution of time consuming process as well. Grid computing have received a significant and sustained research interest in terms of designing and deploying large scale and high performance computational in e-Science and businesses.

This paper introduces the design and analysis of a Photovoltaic PV system to supply the residential load of a house in Golpayegan, Iran. The optimization found that the PV array required capacities are 5. Power system planning and control is largely based on power flow analysis and short-circuit calculations, but an accurate model of the system is needed in order to obtain usable and reliable results.

Calculation of inductances and Calculation of inductances and capacitances of real-life overhead lines is very complex and demand large amount of usually unknown data and therefore estimation of parameters of overhead line using particle swarm optimization and historical data of voltages, currents and powers is analyzed. Values for parameters of the particle swarm optimization algorithm are proposed and sensitivity of this approach to input data errors is investigated.

Data for three real-life distribution overhead lines are collected using smart meters, protection relays and SCADA system. However, these measurements are rejected as unreliable for estimation and main reasons of poor quality are identified.

Renewable energy-based local microgrids are gaining popularity despite the unavailability of low-cost, power efficient, and secure communication system for its supervisory control and data acquisition SCADA system. This research has This research has been carried out to address this issue along with the additional features such as data uploading to a server through a gateway, local data logging, and alerting the concerned crew in case of any fault to minimize the outage time.

Communication security has been achieved by implementing AES cryptography. Data authenticity has been achieved by introducing a unique message authentication code MAC for each message.

A mesh-like network has been implemented to improve the LoRa range. ESP32 and dragino-uno based LoRa gateways have been tried for uploading the data to the server, and local data storage has been achieved using an SD card.

Detailed system design and test results are presented in this paper. In past decades, Nigeria's power grid has been suffering from epileptic power supply due to the load demand as a result of population increase without creating a solution for grid expansion. If this trend continues, it will lead to more If this trend continues, it will lead to more frequent grid collapse.

There are also other challenges caused as a result of short circuit issues, system over load, high voltage surge, over voltage, weather hazards such as rain storms that cause the falling of trees on power lines interrupting power and solar storms that cause electromagnetic interference.

Therefore, there is need to decentralize Nigeria's national power grid system and incorporate a central smart grid system and interconnect them by exploiting the regional power resource potential in every region of the country including Niger state and connecting them in such a way that they will use automation control with the deployment of the smart grid to detect faults after rain storms, absorb electromagnetic interference from solar storms, detect system overloads and also provide grid expansion infrastructure to buffer the increasing population that could cause grid collapse or system overload that is, if more people are added to the region without increased energy access.

The result of this research work designed a power grid system of central smart grid monitoring system, a mini grid automation control system to be able to distribute power adequately or limit power when there is reduced load usage.

The design also has three power mini grid systems strategically placed in different locations of the country that has a significant power resource potential. If this smart grid infrastructures are deployed this will tackle and solve the power problem in the Nigeria. In a multiple parallel-connected inverters system, limiting the circulating current phenomenon is mandatory since it may influence efficiency and reliability. In this paper, a new control method aimed at this purpose and conceived to be The hardware implemented is the same for every inverter; therefore, the addition of a new module does not require redesign, enhancing system modularity.

The system has been simulated in a Simulink environment. To study its behavior and to improve the control method, simulations with two parallel-connected inverters have been firstly conducted, then additional simulations have been performed with increasing complexity to demonstrate the quality of the algorithm. The results prove the ability of the method proposed to limit the circulating currents to negligible values.

Leonardo Saccenti. There are major challenges when using renewable energy for power supply. When it is cloudy usually after rain, solar production is low yet there is need to use power when the demand for power is required; weather conditions can be a When it is cloudy usually after rain, solar production is low yet there is need to use power when the demand for power is required; weather conditions can be a problem at that period.

An Automatic Transfer Switch ATS for a single-phase power generator has been designed to enable the automatic operation and transfer of power supply between a primary source of power supply and a secondary source power generator. Clean and environmental energy sources campaign associated with their availability at almost zero cost have resulted in the increase of Renewable energy use throughout the world.

In Nigeria and specifically in most parts of the country, Solar Energy constitutes a tremendous resource. When it is cloudy usually after rain, we usually experience low sunlight; hence there is need to maintain continuity of power supply switching automatically to the stand by source. The p rimary power source is the Solar PV system and the generator is the secondary. This research work provided the means to transfer power in a safe manner using relay logic technique.

When solar production is low below V , the system switches to the diese l or petrol system until it detects voltage within the allowable limits from the Inverter and switch back to Hybrid Renewable Energy System HRES. The design is simulated using visual basic to validate the performance of this work. Contacts of generator circuit closes when voltage is below normal Vac. Ezekiel Nnamere Aneke Ph.

Power failure or incessant power failure in our country are caused by power loss, low power factor, overcurrent, over voltage to mention a few. The digitalization of the power grid to smart grid provides value added services to the prosumers and other stakeholders involved in the energy market, and possibly disrupts existing electricity services in smart cities.

The use of The use of Electric Vehicles EVs do not only challenge the sustainability of the smart grid but also promote and stimulate its upgrading.

EVs have environmental benefits as compared to hybrids or even internal combustion engine vehicle as they can help minimize noise levels, pollution, and greenhouse gas emissions.

The integration of EVs could bring substantial changes for the society not only in providing transportation services but also shifting economies from petroleum and reducing the carbon dioxide CO 2 emission from the transportation sector. Therefore, this study employs secondary data from the literature to explore how EVs can achieve sustainable energy as a service business model in smart cities. Findings from this study suggest that EVs are major assets for a sustainable energy future as EV batteries offers an untapped opportunity to store electricity from renewable energy sources.

Implications from this study discusses the issues and recommendations for EVs integration in smart cities.
