The proposed GHR system is incorporated with a pumped hydro-storage system (PHS) to store excess energy. The proposed algorithm aims to resolve the load demand uncertainty in order to minimize the electricity bills of the consumer and to maximize the energy sales into the grid, under time-of-use (TOU) tariff scheme. Therefore, the maximization of load demand satisfaction is not compromised. The traditional open loop optimization approach cannot cater for load demand uncertainty. It becomes more challenging to adequately meet the uncertain load demand. Within this context, the rule-based control algorithm is developed to manage power flow during uncertain load demand. The obtained results demonstrated that the load demand is adequately met at a reduced grid consumption cost, through the application of the rule-based control algorithm. This confirmed that the proposed algorithm benefits the user, by reliably and economically satisfying the load demand at a minimal grid energy cost.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"485 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116193105","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 study used the building of Engineering Faculty of Universitas Andalas, Indonesia, as the object of research. In these models, the amount of electric energy consumption for a month is estimated as needed. Estimation of electric energy requirement is mapped from faculty activities, activities schedule, standards for power quality, standard lighting, room temperature standards, load technology and human behavior in the building. The parameters used in the calculation are obtained from direct observation in the field. Furthermore, the real-time monitoring of electrical energy system is designed with the installation of power logic on the substation faculty buildings and transmitted energy data through the campus web. The measurements of power and electrical energy consumption for one week using Fluke Power Analyzer 435 series II is needed for the design base of energy monitoring system. In this study, the difference between the results of real-time monitoring and the estimation of energy consumption in the object of study during October 2018 was 9,151,664 kWh (21.86%). This is a form of waste of electrical energy because of the use of electric energy in the room and time that is not appropriate. The initial solution to the waste indicated above is the management approach. However, this designed model is able to integrate all possible paths to reduce electric energy consumption, such as: improving power quality, increasing efficient technology in the load, and reduction of energy waste.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121950961","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}

One of the problems is that solar energy and wind power only generate energy when it is windy or the sun is shining. This work presents a possible solution to this problem. Solar energy and wind power are increasing power generation forms globally. Yet, some technical challenges exist in integrating solar energy and wind power in the electricity network. For example, wind speed changes the rotating speed of windmill plates causing changes to the voltage, frequency, and power. However, an integrated renewable energy supply and energy storage system connects solar and wind to a battery system, ensuring electricity production without adding non-renewable sources. Applications can be near consumption places like houses, remote towns, factories, and research stations. In this study, renewable energy and energy storage system integrates vehicle to grid operations to reduce fluctuating power. As a result, grid connections to large-scale and small-scale solutions are presented. Presented grid connections stabilize fluctuating power system. Increasing penetration of renewable energy needs balancing power. The combination of renewable power, batteries, and electric vehicles are a solution for balancing fluctuating power frequency and voltage.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117218680","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}

It is important to investigate the feasibility of these energy policies and understand relevant issues because that will play an important role to realize a sustainable and cost-effective energy system for Europe. In this regard, this paper aims to analyze EU's major energy policies―namely, increasing the renewable energy contribution and improving the energy efficiency―designed to support the greenhouse gas emission reductions. The recently established energy polices of two major states―Sweden and Poland―are specifically addressed and compared that the government currently considers. In addition, this paper examines the advantages and disadvantages of these energy policies, and presents an improvement with a focus on their implications for developing countries. Finally, this paper suggests the direction of the energy policy mix for European countries based on examples of the technology transfer programs on inter-nations and the green climates fund.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129487314","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}
