The main reason is efficiency. Nowadays, combined cycle power plants can achieve more than 60% efficiency what makes them one of the most efficient. It is important due to limitation of fossil fuels resources as well as environmental protection. Such constrictions are able to decrease CO2, SO2, NOX and dust production. That makes them suitable for a policy of decreasing global warming which affects people all around the world. The operation of combined cycle power plant is affected by many factors which are not only related with construction of a system but also ambient conditions. In present study, three different combined cycles were modeled in the Gate Cycle software: single-pressure with supplementary firing, dual-pressure and triple-pressure reheat cycle. Ambient temperature, pressure ratio in the gas part and temperature at the inlet to the gas turbine were investigated as the most significant factors which affect efficiency and power production in whole system.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"97 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":"127178928","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}

Replaced the energy generation sources from the fossil fuels to the renewable energy sources is one of the important project that scientists and researchers has been worked and the good potentials of this sources of energy make them to most studies and researchers from this important. Salinity gradient energy or blue energy is an of the high potential energy sources that placed in renewable energy’s list. The salinity gradient energy can be one of the important sources of the renewable energy to electricity generation for global electrical demand in future. When saline and fresh water mixes the Gibbs free energy is released. This energy could be used for generation of electrical power by some methods. There are two promising techniques for the generation energy from salinity gradient including RED and PRO methods. According the estimates of power available in the world salinity gradients energy are estimated between 1.4 and 2.6 TW, this amount of power generation in comparison to other marine renewable energy sources is a good potential. This paper is over review for salinity gradient energy, RED and PRO methods.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"2 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":"130001554","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}

On the long-time scale, an optimal reactive power dispatch (ORPD) model considering the chance constraint of voltage is proposed, which sets minimum operating cost as its target, including the adjusting cost of discrete devices. On the short-time scale, an adaptively slack optimal control strategy for PCC reactive power and voltage (Q/V-ASOC) is proposed, which can adaptively adjust the PCC reactive power and voltage according to the real-time changes of PV and load output. By comparing the control effect of different coordinated control methods for multiple PVs, an advise on the decision of reactive power and voltage coordinated control scheme for DN with high penetration level of PV can be provided.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"192 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":"132866795","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 current technology for a WTG may utilize only 80% of theoretically maximum wind energy, and thus, related studies have been conducted to maximize its electricity production. If the price of a WTG becomes expensive due to advanced technologies, the improved profitability of a wind plant project is not a natural outcome from the increased energy yield. However, the economic analysis related to the increased wind energy capture has not been sufficiently addressed. Therefore, in this study, we perform the economic sensitivity analysis for the improvement in the energy capture of a WTG. Specifically, we examine the decrease in the levelized cost of energy (LCOE) due to the increased energy production; then, we analyze the acceptable increase in the capital cost of a WTG in the view of economic feasibility. The results show that both the reduction in LCOE and the acceptable increase in the capital cost are linearly proportional to the percent increase in the energy production of a WTG. Further, it is found that the economic effect is possibly the best for time-of-use (TOU) electricity pricing scheme.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"37 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":"130862629","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}
