A topical issue globally is the development and implementation of renewable energy sources for sustainable development. To meet current requirements, the research in this paper is directed towards finding solutions to increase the performance and efficiency of wind power plants by implementing innovative solutions for hollow roller bearings developed through the use of sustainable growth programs in the field of green energy. Another solution that has the effect of increasing wind power performance consists of the implementation of a new large-size lubrication system for large-size bearings in wind energy units, which will increase their durability by developing maintenance capabilities. In this research, we will explore the possibility of introducing an innovative automated lubrication system in hollow roller bearings. The main results of the research, the innovative constructive solutions, will lead to important savings by lowering wind farm maintenance costs, increasing the durability of large bearings, and increasing the energy efficiency and yield of the whole system. The expected impact of implementing the solutions found will mainly be in the field of sustainable growth and environmental development.

The exploitation of distributed renewable energy sources leads to a low-carbon energy transition, mainly based on the optimal integration of hydro, PV and wind power plants with the remaining high-performance fossil-fuel power stations. In the last twenty years, European Union (EU) countries have shown a significant increase of the power installed in new PV and wind power plants, together with the refurbishment of small and medium size hydro stations. In particular, in Italy, PV and wind energy production has strongly increased and nowadays there are regions characterized by a very green energy mix. In this new scenario, energy storage becomes a viable solution to mitigate the variability of renewable energy sources thus optimizing the network operation. The present paper is focused on the Liguria region, in the North of Italy and in particular on the Bormida Valley where nowadays more than the half of the annual electricity consumption is covered by the renewable energy local production. The paper describes the current energy situation and proposes an optimization tool to investigate the possibility of installing new PV and wind power plants, as well as energy intensive storage units based on sodium-sulphur batteries; moreover, different scenarios are analyzed through the definition of economic and environmental key performance indicators.

In modern conditions of falling business activity of enterprises and falling incomes of the population, the growing trend of electricity shortages persists. This need may be aggravated by the high level of deterioration of equipment at Russian thermal power plants. All world practice shifts the guidelines for expanding electricity production towards the creation of a market for pre-fabricated renewable energy sources. In the article, the authors focused on justifying the need for the massive construction of wind power plants as an alternative source of energy. Today, «traditional» energy sources cannot meet the growing demand in remote areas of the Tyumen region with districts in the context of the spread of modern information technologies and the process of digitalization of public services. The current situation also imposes significant restrictions on the intensity of the development of the process of educational technologies in remote settlements. In this connection, the authors of the article decided to conduct an analytical study to substantiate the ways of territorial development through the launch of projects for the construction of compact wind power plants as an alternative source of energy in providing resources to remote settlements.

The paper describes special aspects of using the wind power plants (wind turbines) in the power grid. The paper provides the classification and schematic presentation of AC wind turbines, analyzes the role, place and performance of wind power plants in Smart Grid systems with a large share of renewable energy sources. The authors also reviews a detailed analysis of existing AC wind turbines in this paper. Recommendations are given for how to enhance the wind power plants in smart grids in terms of reliability, and introduce the hardware used in the generation, conversion and interface systems into the existing power grid. After the wind power plants had been put online, the relevance of the Smart Grid concept for existing power grids was obvious. The execution of such projects is assumed to be financially costly, requires careful study, and development of flexible algorithms, but in some cases this may be the only approach. The analysis of using wind turbines shows that the structural configuration of wind power plants can be based on the principles known in the power engineering. The approaches may differ, not fundamentally, but in engineering considerations. it is necessary to point out that the method of controlling dual-power machines is quite comprehensive so that their wide use will face operational problems caused by the lack of highly professional specialists in electric drives. Therefore, it seems advisable to use square-cage asynchronous generators in wide applications. The paper shows that as the renewable energy sources are largely used in power grids, there is an issue of maintaining the power generation at a required level considering the variability of incoming wind energy. This results in the malfunctions in the operation of relay protection devices and emergency control automatics (RP and ECA), and the complicated control. Also, the standards of the CIS countries and regulatory documents miss the requirements for the wind turbine protections, taking into account their specialty causing the inefficient standard protective logic, which does not work correctly in a number of abnormal and emergency operating modes, and especially Smart Grid in power grids.

Abstract. Large-scale integration of renewable energy sources with power-electronic converters is pushing the power system closer to its dynamic stability limit. This has increased the risk of wide-area blackouts. Thus, the changing generation profile in the power system necessitates the use of alternate sources of energy such as wind power plants, to provide blackstart services in the future. This however, requires grid-forming and not the traditionally prevalent grid-following wind turbines. In this paper, four different grid-forming control strategies have been implemented in an HVDC-connected wind farm. A simulation study has been carried out to test the different control schemes for the different stages of energization of onshore load by the wind farm. Their transient behaviour during transformer inrush, converter pre-charge and de-blocking, and onshore block-load pickup, has been compared to demonstrate the blackstart capabilities of grid-forming wind power plants for early participation in power system restoration.

Abstract Decreasing fossil energy resources and increasing greenhouse gas emissions increase the need for clean and renewable energy sources day by day. One of the sources of renewable energy is wind power, which has been constantly evolving in recent years. Wind power plants are sometimes unresponsive during peak hours, so a backup storage system seems essential for these power plants. In this study, a hybrid system is presented for connection to wind power plants consisting of fuel cell and hydrogen production, to provide reliable power and valuable by-products. In this paper, a case study is conducted for the desired system in the Shahryar County. The techno-economic optimization of the above system indicates that in the best design (consisting of three wind turbines), the annual production capacity of the hybrid system will be 1795 MWh, of which 12 % is the share of fuel cells. The results show that the hybrid system increases the capacity factor of the wind power plant by 2.8 %. The calculated cost of energy (COE) and the net present cost (NPC) for the hybrid system would amount to $ 0.77 and $ 5 235.066, respectively.

The article contains the following technical proposals for the power supply of autonomous agricultural facilities using renewable energy sources: the use of hybrid solar-wind power plants, the use of vortex wind power plants with a vertical axis to use both the energy of horizontal wind flows and the energy of upward air flows. The structure and operation algorithm of an autonomous power supply system based on a hybrid solarwind power plant and a diesel generator for autonomous agricultural facilities of small and medium power in regions where there is no distribution electric network are proposed. This system will allow for insufficient wind load to ensure reliable power supply to an autonomous agricultural facility with minimal use of diesel fuel. The design of a vortex wind power installation has been developed. The fastening on the shaft of the wind power installation of a conical helical blade with a variable radius, decreasing in the direction from the lower to the upper cut of the socket, improves the efficiency of the installation. The proposed installation makes it possible to use small winds and low-potential thermal ascending air currents, reduce low-frequency vibration and noise, and also increase the stability and efficiency of use of wind energy.
