The integration of Renewable Energy Sources (RES) brings along abnormalities that affect the grid, loads, and may degrade the performance of the system. These issues can be alleviated with the integration of RES with the use of a distribution Static Synchronous Compensator (STATCOM). Renewable generation with STATCOM provides quality of power during disturbances created by the AC loads and intermittent power from the RES. The STATCOM distribution of DC link plays a major role in the supply quality during abnormalities. In this work, an attempt has been made to provide supply quality in the distribution system with the integration of a renewable energy farm using Artificial Neural Network (ANN)-based DC link STATCOM control of distribution. The wind farm is analyzed for a Double Fed Induction Generator (DFIG) based wind turbine system and it is integrated into the distribution system. The system was simulated in MATLAB 2018A.

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.

The Government

The idea of achieving energy security and lowering the dependence on the global hydrocarbon market is at the top of the agenda in many countries. Most of them consider switching from traditional energy sources to renewable ones as one of the ways to reduce fuel import. This concept absolutely conforms to one of the UN Sustainable Development Goals (Goal no. 7, “Affordable and Clean Energy”). In May 2019, the Government of Uzbekistan Republic adopted the law on the Use of Renewable Energy Sources (RES). By 2030, Uzbekistan is going to increase the share of RES in the total structure of electricity generation up to 25 % (currently it is at 10 %), by building solar and wind farms with a total installed capacity of 5,000 MW and 3,000 MW, respectively. The energy-deficient Bostanliq district of the Tashkent region has become one of the places of interest, where transport infrastructure, recreation services, and renewable energy will be developed. The purpose of this study was a multivariate analysis, considering the meteorological, ecological, and socio-economic characteristics of the Bostanliq district, leading to the selection of the optimal location for the wind farm. The assessment map based on the results of this analysis made it possible to identify areas that are most suitable for the location of wind power plants. The assessment method, that was used in this work, is also applicable to other regions of the world.

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 analyzes the problems and risks of new-fangled renewable energy sources in the 21st century, which can radically change the energy picture of the world and to a certain extent reduce the risk of climate change. However, energy generation from wind is usually available 25—35% of the time, from the sun — 10—25%.Renewable energy sources (RES) face the problem of accumulating or supporting capacities that should replace the unstable generation of RES at the time of inevitable failures. RES cannot exist without excess reserve capacities on traditional energy carriers that can quickly increase and reduce electricity production. Abandoning hydrocarbons in the next 30—50 years looks unrealistic if countries want to maintain their competitiveness. The growth of the share of RES in the global energy balance is an extremely politicized phenomenon.The development of renewable generation creates risks for consumers. Especially for large ones. One of these risks is associated with the intermittent, unstable nature of renewable generation, which in recent years has been understood mainly as solar and wind power plants. In addition, to produce more solar panels, wind turbines and batteries for electric vehicles, humanity will need more specific resources — rare earth metals. The production of these metals is unsafe for the environment. It involves the consumption of a huge amount of water and electrical energy.Renewable energy sources may dominate, but it will take centuries. Demand is already growing, but fossil fuels will live long enough.

The goal of this paper is to introduce the market modeling tool Antares and to point out possibilities of its utilisation in cost-benefit analysis of energy projects. Market modeling of power systems represents a detailed modeling of generating units, consumption and cross-border connections with neighboring systems in order to find economically optimal dispatching of power plants by which the total consumption will be satisfied. In this paper, two power systems connected by cross-border transmission lines will be modeled (in one of them there is a large amount of installed capacity of renewable energy sources). The benefits of reinforcing cross-border connection embodied in avoiding curtailment of available renewable energy due to low energy consumption and lack of energy storage systems will be analyzed, along with corresponding benefits of reduced CO2 emissions due to the ability to transfer green energy into neighboring power systems through increased cross-border capacity.
