The reduction of energy resources and the increase in environmental consciousness have recently increased the interest in renewable energy sources. Wind energy is from renewable energy sources, which are used in many countries. Turkey has a lot alternative wind energy plants thanks to its favorable geographical location. Where the wind power plant is to be established is a complex and important decisive factor. It is very important to select the appropriate wind power plant site to take advantage of wind energy and reduce costs. In this study, we aimed to reach the solution of wind energy plant site selection. For this purpose 4 alternative wind power plant locations have been identified. To evaluate the alternatives, 10 criteria in four dimensions including wind potential, location, cost, and social benefits are selected. Since the Multicriterion Decision Making (MCDM) methods are often used in problem of location selection from past to present, TOPSIS method combined with intuitionistic fuzzy set (IFS) has been used to achieve this goal. The main purpose of the TOPSIS method is to rank the alternatives in the worst way. The IFS are used to reflect approval, rejection, and hesitation of decision makers by dealing with real life uncertainty, imprecision, vagueness, and linguistic human decisions. Finally, a numerical example is applied for wind power plant site selection. In order to demonstrate the effectiveness of IFS, the problem is solved by the Fuzzy TOPSIS method using the same data. Then, the obtained results are compared with the IFS method to show the effectiveness of the proposed method.

The article focuses on implementation and operation of the wind power plant of the original design for mounting on the chimneys of seaport power facilities. The worked out wind power unit makes it possible to use secondary thermal energy (heat from the exhaust gases of a boiler house, a mini-thermal power plant based on gas reciprocating plants, etc.) to generate electricity in an amount sufficient to satisfy or partially compensate the needs of the power facility. The aspect of the wind power plant design and the concept of energy generation have been worked out. The hot surface area of the stack serves as the source of energy for upward air flows in the developed original design of the wind power plant. The wind power plant placed on top of the stack is an additional environmentally friendly way of using the potential of renewable energy sources for electric power generation. This method differs from the existing ones in that the pipe is used not as a high support where higher wind speeds prevail, but as a source of thermal energy from secondary energy resources (flue gases of the fuel plant). Wind power plant design includes chimney, generator rotor, permanent rotor magnet, thrust collar for stator winding assembly, thrust collar for bearing assembly, brake drum, brake shoe, brake drive lever, rotor brake drive cable, brake handle and other elements. The introduction of such power units will partially or fully compensate for the own needs of the power facilities that generate thermal and electric energy for the reliable and uninterrupted operation of port services

This paper tests the hypothesis that incentives for renewable energy sources contribute to economic development in Croatia. The aim of the paper is to quantify the total effects of wind power plant deployment on the Croatian economy in terms of employment and gross value. Indirect and induced effects are spread over the value added chain of producers of investment and intermediate goods and services required for wind power plant deployment and operation. The open input-output model is used for quantifying indirect effects. The closed input output model, which assumes endogenous personal consumption, is applied for quantifying total effects, which includes the effects of induced personal consumption. The gross value added and employment type I and type II multipliers related to wind power plants in Croatia were calculated separately for the investment and intermediate consumption channel. The results show positive indirect and induced effects relating to the deployment of wind power plants in Croatia. They are less pronounced in comparison to previous studies due to the undeveloped domestic production of equipment required for wind power plant deployment. Apart from the manufacturing sector, which produces equipment incorporated into wind power plants, the total effects were significant for construction, transport, and other supporting industries.

In this work, the coupled operation of a wind park and a hydrogen power-to-gas (P2G) technology is addressed in order to improve dispatchability and profitability of the wind resource. Among many available storage technologies currently under development, the P2G was chosen because of its large storage capacity and fast response. In particular, oppositely to traditional storage approaches, the solution that considers the direct injection of hydrogen in the natural gas grid infrastructure could reduce investment costs and improve the renewable fraction of fuels. Economic optimal operation and installed P2G power are calculated solving a mixed-integer linear programming (MILP) problem. Performances of the main component (electrolysis unit) are modeled, including additional costs for start-up and partial load operation losses. Technical limits on both electric and natural gas grids are also included. Some assumptions on the economic rules governing the electric grid unbalance are made, according to possible evolutions of the regulation framework focused on EU and Italian system. The simulation is performed on hourly basis, assuming realistic forecasted and real power production profiles from an actual mid-size (30 MW) wind power plant, together with prices of electricity markets and gas production. A sensitivity analysis is also performed varying both economic and technical parameters. Whereas in some scenarios the technology is profitable with the current investment costs, a reduction of electrolyzer costs down to expected mid-term targets would lead to a stronger competitiveness in each scenario. The study aims at identifying the influence of main technical and economic parameters on the effectiveness of the power-to-gas technology. Results show how the proposed solution allows better exploiting the wind resource, although the net electricity production can decrease due to the production of hydrogen, suggesting the possibility to substantially oversize the wind park in order to cover the same electric load.
