Nowadays, river floods are one of the major challenges for modern society. Despite the significant achievements in the river flood forecasting and early warning systems, there is still a need of effective tools and measures either to prevent the floods or at least to decrease its negative impact on the agricultural and urban areas. This information can be used by storm-water and flood pumping stations to avoid the damage that can occur after the flood. One of the main issues is the condition monitoring of these pumping stations. In some cases, these stations are not ready for an instant response to natural disasters like floods. In order to prevent unexpected failures of the electric drives or the pumps themselves, it is necessary to monitor the state of the equipment. The proposed method is aimed to create a smart monitoring system for fault diagnosis of pumping stations. It can be helpful to avoid floods especially near the border of Estonia and Russia because floods generally occur in border areas like Tartu town and county, Lake Peipus, Pskov town and county, mining areas in North-East Estonia.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128687934","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}

An emphasis is made on more efficient and flexible FACTS (Flexible Alternating Current Transmission System) devices - mainly static var compensators (SVC) and static synchronous compensators (STATCOM). In addition, it is necessary to solve a number of problems related to the search for the optimal location of an RPCD and the selection of its parameters. It should be carried out for the purpose of achieving the highest technical and economic effect for a power system as a whole or its region. The multiobjective optimization (MOO) methods, particularly heuristic ones (genetic algorithms, particle swarm methods, simulated annealing etc.), are proven to be efficient in the analysis of power systems planning. The drawbacks of these methods are well known, namely their dependency on forms of objective functions. The importance of taking N-1 criterion into account in questions of optimal placement of an SVC was shown in the article. As a consequence, the security indices were suggested to use as the additional objective functions. Moreover, the range of probabilistic parameters is not limited to expected values of the objective functions components but also it includes moments of higher orders. The test results have shown that the forms of objective functions and plenty of the factors taken into account (e.g. post-contingency states) significantly influence the problem solution. It was demonstrated that the optimization results possess great degree of uncertainty in the case of large number of criteria for the selection of a bus for an RPCD.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"88 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128000398","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}

Energy efficiency is also one of the ways how energy-intensive manufacturing companies could overcome the rising costs of energy, driven by ambitious climate policy. In Latvia, energy efficiency policy goes along with energy-intensive consumer rights on energy taxation exemptions that should ensure their competitiveness. However, both policies are in some way contradictory and, in certain circumstances, when an energy-intensive company faces the risk to lose its status of being energy-intensive company, energy efficiency policy will fail as the company's willingness to become more efficient will be reduced. However, the peculiarities of the Latvian tax policy, whereby the right to receive the tax rebate is not available at the moment of consumption but post-factum, which does not provide full sustainability, may weaken company's willingness to maintain energy intensity above the threshold and provide tax refunds as an additional source to finance energy efficiency measures.","PeriodicalId":317349,"journal":{"name":"2019 IEEE 60th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131416914","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}
