Rather than adhering to conventional load scheduling practices or minimizing grid power usage at each time interval, a novel approach is adopted wherein the optimization is performed for the entire 24-hour period simultaneously. By directly incorporating time-of-use rates into the cost function, an absolute optimal solution is attained. The findings indicate that compared to single time step optimization, the proposed method results in a reduction of the power bill ranging from 6% to 10%, depending on load-generation variations. Furthermore, if the utility or government enforces the summer tariff consistently throughout the year, the savings escalate to a range of 15% to 22%. Introducing a more intelligent tariff structure can thus serve as an effective means to expedite the transition towards renewable energy by incentivizing individual investments in solar PV, battery systems, and smart home energy management.","PeriodicalId":168459,"journal":{"name":"International Journal of Energy and Smart Grid","volume":"39 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of wind, water, earth, solar and other clean energy has become possible, and finally, the world is on a path that requires new research in this field. Between the urban and social elements, per capita energy in the housing sector is allocated the highest consumption in the world, and this sector has the greatest amount of energy consumption in Iran as well. Researchers are presenting new solutions in addition to the usage of technology in the production of renewable energies, making closer to reality the reproducible ideas about using parts of buildings and natural forces around the buildings. This study is an attempt to explore the surrounding natural forces and materials that are used in construction, alongside the study of books and valid and scientific global websites that discussing the idea of using new technologies along with the existing energy production. Using renewable energy, homes have been made from special materials, where the manner of design adjusts to the environment (like solar energy), but can still function in any condition. We have seen that by studying the available information, biogas and photovoltaic systems are also intended to (in addition to their own sufficiency) and lead to saving energy.

The system is known to facilitate the connection of renewable energy sources to the national grid from a specific region, it is made up of Energy Storage System, Distributable Energy Resources, and Control System. Energy sources are classified as Distributable Energy Resources and various assets can be linked to the platform such as small-scale microgrids or community-based power platforms with demand-side management portfolios. A Virtual Power Plant platform has the power-distributing capability and an evolutionary trading platform (Peer to Peer trading). It has also proven to cut down carbon emissions as more renewables find their way to the grid. Additionally, data analytics and forecasting tools on the Virtual Power Plant are used to give information to the end-users on their storage, demand, and expected future generation, the user can interact with the system through a Human Machine Interface that has easy to use dashboard. Currently, the VPP systems have been implemented as pilot programs in countries such as Sweden, Norway, Belgium, and the USA. The potential application of the system can be extended as a case study and futuristic smart grid system for Kenya, as the National grid is substantially fed from renewable energy sources, and the vast majority of rural areas can benefit from cheap and affordable energy.

According to recent development in solar energy policies in the countries, solar thermal and other solar Technologies can be an attractive solution for the industrial market. To meet some needs in manufacturing processes, textile and food transformations. CSP Technologies as a central receiver (CR) and parabolic trough collector (PTC) have already experimented in turkey  for these purposes. The present work is illustrated as a synopsis of techno-economic and optimization analysis of a small PTC-CSP  system arrangement using a combined Rankine cycle for electricity production in Izmir. This study carries out a comparative cost of optimization  work per kW. Thus, the improvement of the plant assessment study has considered, technical, thermodynamical and economical parametric to highlight the most important factors in the choice of the components that constitute the technology and the arrangement of the modules on the solar field. T he System Advisor Model ( SAM), Meteonorm7 file, and Excel simulation programs have been used to determine some economic parametric such as the Levelized cost of electricity ( LCOE ), internal rate return, net present value and the payback period. The results shown that for a 1MWe solar PTC power plant in Izmir, the initial investment cost is approximately 3.9 Million US Dollar, with  an estimated LCOE of 13.5 USCent Dollar and an Annual Operation Expenditure of 37.5 USDollar /MWh. Moreover, the Required Cost for Optimization per kW h (RCO) of exergy destroyed and energy loss of configuration#1 were found to be 1830.2 and 1887.5 US Dollar showing that it is possible for improvement works to be achieved. The values corresponding to the optimization of the solar field configuration #3 and #2  are close to the minimal required  Cost for Optimization per kW th (RCO) .  This means that no further improvement can be achieved. Due to some constraints faced during this study, it can be better to arrange the solar thermal power plant following the solar multiple (SM) and the installed cost per kW.","PeriodicalId":168459,"journal":{"name":"International Journal of Energy and Smart Grid","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127994581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, some barriers to wide deployment of energy storage systems within microgrids are presented. Microgrids have already gained considerable attention as an alternate configuration in electric power systems that can operate in grid-connected mode or islanded mode. Host grid reliability, electricity rate uncertainty, electricity demand beyond installed capacity, and regulatory and market incentives are some of the drivers motivating the deployment of microgrids. Microgrids offer greater opportunities for including renewable energy sources (RES) in their generation portfolio to mitigate the energy demand reliably and affordably. However, there are still several issues such as microgrid stability, power and energy management, reliability and power quality that make microgrids implementation challenging. Nevertheless, the energy storage system is proposed as a promising solution to overcome the aforementioned challenges.","PeriodicalId":168459,"journal":{"name":"International Journal of Energy and Smart Grid","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130238695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Industrial plants connected to the national distribution or transmission grid at medium voltage level are really exposed to various grid events that affect firstly production efficiency, equipment, system failure and unexpected malfunctioning. Without data, there is no way to analysis and make clear definition of grid events.
