The basic elements of the project management model for the creation of plasma-chemical elements for power plants have been developed. It is shown that the main features of science-intensive projects for the development of energy systems using plasma-chemical elements are: significant complexity of organizational production systems; significant uncertainty of project states and a high probability of risks arising from the influence of factors that cannot be envisaged in the management process; the uniqueness and high cost of the industrial and intellectual resources involved, as well as the problems of cooperation in the context of International projects. A process model for forming the Statute of the project for creation of plasma-chemical devices for power plants was developed to establish information relationships between control processes of one and the different levels, performance indicators, control over their implementation, as well as visualization of processes in the form of detailed subprocesses. The identification of the main risks of project management for the creation of plasma-chemical elements for environmentally friendly power plants in accordance with the life cycle phases has been identified. The risk indicators of projects at macro level, market and project levels have been developed; interconnections and hierarchies between different factors have been established. In order to substantiate the selection of the most significant criteria, a hierarchy analysis method was used, which determined the importance of the criteria for the project team for the creation of a plasma-chemical elements. It has been determined that the own vectors of the criteria are: strategic 39.1%, financial and economic 31%, environmental 16.3%, functional and technological 10.1%, others 3.6%. The developed model takes into account the specific conditions of operation of plasma installations and enables to determine the local and global probabilities of their occurrence at the initiation stage of the project, and also to develop arrangements to minimize their impact on the indicators of the project effectiveness

The Creation

Successful implementation of international projects for the creation of energy complexes with plasma-chemical treatment of coal into synthesis gas and its using as fuel for gas turbine engines requires large capital investments. In this connection, the use of the Monte Carlo method during assessing the investment feasibility and efficiency of implementation of similar projects in conditions of uncertainties and risks presents applied and scientific interest.The Monte Carlo method makes it possible to use a representative sample of scenarios and not to search through all possible variants of the development of events in the future. The merits include the linear dependence of the number of simulations on the number of financial instruments and the ability to take into account both economic and technical indicators. It is determined that the strategic criteria for the success of the project can prevail in relation to economic and functional-technological, especially in the case of the development of a new environmentally friendly plasma-assisted technology. A theoretical model for estimating the economic efficiency of the project for creation of energy complex using inductive (radio frequency) plasma generators has been developed. Parameters characterizing the economic efficiency of proposed power plant with plasma-chemical gasification of coal are analyzed. The project efficiency depends significantly on the parameters characterizing the investment and discounting conditions. The estimation of economic efficiency of the investment project using plasma-chemical technology on a thermal power station with produced electric power of 3.9 MW is carried out. For the considered project conditions, the calculated average value of the profitability index for a power plant with plasma-chemical gasification of coal for 15 years is equaled 1.19 with a probability of 76%. The developed theoretical models can be used to solve problems of enhancement and optimization of management of international projects for the creation of plasma-chemical elements in conditions of uncertainties and risks

Efficiency And Reliability

The article deals with the problem of waste disposal and, accordingly, landfills in the Moscow Region, which have now become the number 1 problem for the environment in Moscow and the Moscow Region. To solve this problem, incineration plants (IP) will be established in the near future. 4 plants will be located in the Moscow Region that will be able to eliminate 2800 thousand tons of waste per year. Burning of waste results in formation of slag making 25% of its volume, which has a very high temperature (1300.1500°C). An arrangement is considered, in which slag is sent to a water bath and heats the water to 50.90°C. This temperature is sufficient to evaporate any low-temperature substance (freons, limiting hydrocarbons, etc.), whereupon the steam of the low-temperature working medium is sent to a turbine, which produces additional electricity. The creation of a low-temperature thermal power plant (TPP) increases the reliability of electricity generation at the IP. The operation of low-temperature TPPs due to the heat of slag is very efficient, their efficiency factor being as high as 40.60%. In addition to the efficiency of TPPs, capital costs for the creation of additional devices at the IP are of great importance. Thermal power plants operating on slag are just such additional devices, so it is necessary to minimize the capital costs of their creation. In addition to equipment for the operation of TPPs, it is necessary to have a working medium in an amount determined by calculations. From the wide variety of working media, which are considered in the article, it is necessary to choose the substance with the lowest cost.

Feed In Tariff

The apparent increase of ecological awareness during the previous decade has led to the need for adaptation of numerous areas of everyday human lives, so they fit the newly developed environmental tendencies. One of the areas in which this necessity was prominent was the power engineering, where, above all, the understanding of production systems was affected, with the turnabout regarding the distancing from the conventional sources and inclining towards the more acceptable renewable sources taking place. However, alongside the undeniable ecological sustainability of these sources, the financial sustainability of their utilization needs to be considered as well, which is why the subject of this paper is the minimization of costs of energy production in these capacities, if the fictious demand area needed to be supplied. It was assumed that this area is separated from transmission and distribution network, with the sole source of energy for the analyzed consumption being the wind, solar and hydro power plants, located in the close vicinity of the examined area. As the objective of the optimization, performed by the method of Lagrange multipliers, the appropriate apportioning of the generation powers in these plants for every hour during the year was selected, so the total yearly costs of supplying the demand were as low as possible. Also, considering the currently promoted methods intended for encouragement of the potential investors to proceed with the projects that encompass renewable sources, the different cases for which the share of renewables included in the feed-in tariff was varied. Finally, in order to provide the full insight into the optimization procedure, for the randomly selected hour of the year and share of feed-in tariff in the generation capacities, the process of calculation of production powers in the described plants and multipliers needed for application of the selected optimization technique was enclosed.

The Creation

In Europe, we are witnessing a growth in the social economy sector, i.e. in socio – economic organizations, which belong neither to the traditional for profit sector (market economy) nor to the public sector (government) (Deforuny, 2001; Young, 2007) - they rather act at the interface of civil society and markets (Jäger, 2010). The main goal of these organizations, called social enterprises or social business, is doing business for socially useful purposes. These initiatives may take the form of traditional Non-Governmental Organizations (NGOs), like foundations and associations, as well as new kinds of organizations for example social cooperatives, partnerships, funds.Social economy is situated between public and business sphere of administration and combines both, social objectives and the ones profit-oriented. Social entrepreneurship is unquestionably a desirable feature of social economy understood as reaching planned economic objectives with the use of available resources. Another feature comprises in using involvement and creativity of excluded persons and thus, solving social problems, among others, structural unemployment and disadvantage of social minorities as well as strengthening democratic processes, bottom-up social initiatives etc. Achieving objectives, both social and economic, requires using modern management instruments and methods.All of the above mentioned organizations or ventures, which achieve their local, social or ethical mission and goals using methods adopted from the business sector (Defourny, Hulgard, Pestoff, eds.2014). One of these methods is project management. The whole sector of social economy, both in Poland and in Europe, is strongly influenced by projectification process: a lot of the activities are performed in the form of projects. For last ten years projectification of social non-governmental sector as well as the economy sector in Poland was reinforced by EU’s funding stream – hundreds of co-funded projects, which aimed at increasing the level of development and improving the condition of social economy, were implemented. Some of these projects have resulted in the creation of durable, dynamically operating social enterprises, and some of them did not produce any long-term results. In case of successful projects, we can observe an unusual effect of projectification process: the creation of permanent structures, sustainable social economy organizations through the implementation of projects.Although we can identify examples of interesting research on impact of project work on NGOs (Brière, Proulx, Navaro, & Laporte, 2015); Golini, Kalchschmidt, Landoni, 2015) or critical success factors of non-governmental projects (Khang & Moe, 2008), there is a research gap which we would like to address in this paper: lack of research on project management best practices in social enterprises. Thus, the main research question we would like to investigate in the paper is: What are the factors that lead to creation of durable, permanent social economy enterprises from projects?This paper draws on set of qualitative data from broader research on social economy sector conducted in Poland in years 2011-2013 by researchers from the Institute of Public Affairs (IPA). For the purpose of this paper we have conducted multiple case study analysis and analysed 36 case studies of existing social enterprises. One of our research goals was to find out, which factors are critical in the process of creation durable social enterprises from projects. Also, we wanted to understand how projectification, influenced strongly by the EU policies, changes the landscape of social enterprises in Poland and helps them achieve success.

Process Modification

Thermal power plants are of great environmental importance in terms of the huge amounts of wastes that they produce. Although there are process-wise differences among these energy production systems, they all depend on the logic of burning out a fuel and obtaining thermal energy to rotate the turbines. Depending on the process modification and the type of fuel burned, the wastes produced in each step of the overall process may change. In this study, the most expected process and non-process wastes stemming from different power generation processes have been identified and given their European Waste Codes. Giving priority to the waste minimization options for the most problematic wastes from thermal power plants, waste management strategies have been defined. In addition, by using the data collected from site visits, from the literature and provided by the Turkish Republic Ministry of Environment and Urbanization, waste generation factor ranges expressed in terms of kilogram of waste per energy produced annually (kg/MWh) have been estimated. As a result, the highest generation was found to be in fly ash (24–63 for imported coal, 200–270 for native coal), bottom ash (1.3–6 for imported coal, 42–87 for native coal) and the desulfurization wastes (7.3–32) produced in coal combustion power plants. The estimated waste generation factors carry an important role in that they aid the authorities to monitor the production wastes declared by the industries.
