This paper proposes an efficient optimi zation technique to optimally allocate multiple DG units into a RDS. The proposed optimization method considers the integration of solar photovoltaic (PV) based DG units in power distribution networks. It is based on multi-objective function (MOF) that aims to maximize the net saving level (NSL), voltage deviation level (VDL), active power loss level (APLL), environmental pollution reduction level (EPRL), and short circuit level (SCL). The proposed algorithms using various strategies of inertia weight particle swarm optimization (PSO) are applied on the standard IEEE 69-bus system and a real 205-bus Algerian distribution system. The proposed approach and design of such a complicated multi-objective functions are ultimately to make considerable improvements in the technical, economic, and environmental aspects of power distribution networks. It was found that EIW-PSO is the best applied algorithm as it achieves the maximum targets on various quantities; it gives 75.8359%, 28.9642%, and 64.2829% for the APLL, EPRL, and VDL, respectively, with DG units’ installation in the IEEE 69-bus test system. For the same number of DG units, EIW-PSO gives remarkable improved performance with the Adrar City 205-bus test system; numerically, it shows 72.3080%, 22.2027%, and 63.6963% for the APLL, EPRL, and VDL, respectively. The simulation results of this study prove that the proposed algorithms exhibit higher capability and efficiency in fixing the optimum DG settings.","PeriodicalId":52299,"journal":{"name":"Polityka Energetyczna","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45868582","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 growth of the energy needs of society is parallel to the awareness of the need to ensure the environmentally friendly development of society. There are a number of reasons for the search for new energy sources, including the limited reserves of traditional sources, dependence on oil-exporting countries, the greenhouse effect of the energy sector in Ukraine have necessitated a detailed study on the possibility of increasing the yield of biofuels from crops. The economic and mathematical modeling of the possibility of increasing the yield of bioethanol and vegetable oil from agricultural crops has been carried out. An economic optimization model has been formed, which made it possible to study an increase in the yield of bioethanol from sugar-containing and starch-containing crops and vegetable oil from oil crops from 1 ton per 1 hectare of area. Also, an assessment of the lost yield for the investigated crops has been carried out using the method of analysis of the functioning environment (Farrell’s method).","PeriodicalId":52299,"journal":{"name":"Polityka Energetyczna","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49605910","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}

As a response to these changes, the European Union (EU) has already cut the GHG emission by 24% compared to 1990 levels. However, the goals are far greater since the Paris Agreement states that global warming should be kept down to near 2 degrees Celsius, ideally 1.5 degrees Celsius, compared to pre-industrial levels. By 2050, the proportion of global energy produced from coal must decline by between 73 and 97 percent to accomplish this objective. The global employment structure would definitely be affected by this decarbonization in the long run. In this paper, we concentrate on a preliminary evaluation of Poland’s future job market. As Poland’s economy is still driven by coal, energy conversion will have a significant influence on the country’s economy. However, decarbonization is both an opportunity and a items for the system. According to the preliminary investigation of Poland’s future labor market, the future of Polish energy is the cohesion of clean energy sources and decentralized energy, while offshore wind energy in the Baltic Sea can play an important role in the national energy transition, as well as contributing to the country’s energy security and reducing environmental pollution.","PeriodicalId":52299,"journal":{"name":"Polityka Energetyczna","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42601323","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 order to stimulate the production of biofuels, a set of measures has been developed, including legislative regulation, indicative planning of production volumes, preferential taxation and budget support. Ukraine is among the top ten largest consuming countries of energy resources. Weak and inconsistent state policy in the sphere of biofuels as well as inconsistent legislative provisions regulating activities in the field of production, circulation and use of biofuels, impede the effective development of further functioning of the regulatory framework with the legislation of the European Union on the rational use of fuel and energy resources, the limitations of which increase due to inconsistencies between centralized and regional distribution. Therefore, further processes of effective economic development of Ukraine will largely depend on solving the problem of the sustainable provision of available renewable energy resources. Future development of the biofuels market in Ukraine will strongly depend on the institutional and legal conditions in the field of production, circulation and use of biofuels.","PeriodicalId":52299,"journal":{"name":"Polityka Energetyczna","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49182018","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}
