The monitoring 46 indicators of energy security is based on the annually replenished database to calculate indicators. Fuel consumption indicators are grouped in the separate block. Forecasting is based on values of fuels consumption for time series and used extrapolation growth factors CAGR. Pollutant emissions are additional area that can be analyzed through the built-up forecasts of fuel consumption. In this paper attention is paid to the analysis of 25 pollutants under the list of EMEP-2016. There are many recommendations on expanding the use of biomass instead of coal and gas. Almost the whole biomass is burned in the residual sector. Biofuels is practically the only available energy resource in the country. The calculations allow to do conclusions: 1)The replacement of natural gas with biomass adduce to the growth of all pollutants;2) The replacement of coal with biomass decreases emissions for 13 pollutants, but increases emissions for the other 8 substances (TSP, PM10, PM2,5, BC, Cd, Cr, Zn, HCB);3) Recommendations for the expanded use of biomass and the replacement of coal and natural gas should be reviewed.","PeriodicalId":403279,"journal":{"name":"2017 International Conference on Electromechanical and Power Systems (SIELMEN)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126555786","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 one hand, a real voltage wave is analyzed, taken by oscillography and on the other hand two waveforms are identified, alternative step type, by multiplying and their composing, any form of output voltage can be obtained from PWM inverters. The two signals types are first analytically defined in general case and then their corresponding Fourier series are determined. Having the analytical expressions of the Fourier coefficients, as control quantities functions, could identify the realization conditions of two optimum conditions, as fundamental maximum or deforming residue minimum. The two constitutive signals types, proposed, presents Fourier series of similar forms, which indicates these contain harmonics with the same order and phase, but with different weights, of which coefficients are summarized when such signals are to be overlapped. Because there is a dependency of the harmonics coefficients on the control quantities, as conduction and pause times, it becomes possible to apply some control optimum criteria for the PWM invertor output voltage to satisfy some energy requirements.","PeriodicalId":403279,"journal":{"name":"2017 International Conference on Electromechanical and Power Systems (SIELMEN)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128163075","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 assurance of a proper management, in accordance with the local and specific conditions may provide a high efficiency, and a smaller time to recover the initial investment. The paper structured in six parts aims to highlight the importance of surveillance, designing, modeling, and efficiency of SHP, in the context of the sustainable development of the energy sector. For the local communities, private investors, social communities and local authorities, hydropower plants represent in many cases, the main source of energy. First is analyzed the efficiency of the local energetic infrastructure, in the current economic context. A presentation of the optimal solutions for designing and modeling, followed by the Demand Site Management-DSM is mentioned. The main factors that influence the optimum functioning of the SHP, correlated with the local conditions are introduced as the input-data. A briefly presentation of the numerical model is mentioned, with the main considered parameters. Some of the obtained results for a specific area will highlight the efficiency of the proposed solution, the real benefits of the combined tasks. The paper ends with some conclusions, and references.","PeriodicalId":403279,"journal":{"name":"2017 International Conference on Electromechanical and Power Systems (SIELMEN)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128345747","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}
