In distribution power grids supplied by dispersed power sources, for example RES (Renewable Energy Sources), in the event of a load dump, unexpected transient states may appear. These states involve a dangerous increase in voltage or current. This situation may lead to the disconnection of these sources. To prevent this phenomenon, a non-linear anti-windup regulator with a conditional integrator has been proposed. This solution allows a significant improvement of the generator’s dynamic properties both at load dump and on return to full load.

This critical review report highlights the enormous potentiality and availability of renewable energy sources in the Gulf region. The earth suffers from extreme air pollution, climate changes, and extreme problems due to the enormous usage of underground carbon resources applications materialized in industrial, transport, and domestic sectors. The countries under Gulf Cooperation Council, i.e., Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, mainly explore those underground carbon resources for crude oil extraction and natural gas production. As a nonrenewable resource, these are bound to be exhausted in the near future. Hence, this review discusses the importance and feasibility of renewable sources in the Gulf region to persuade the scientific community to launch and explore renewable sources to obtain the maximum benefit in electric power generation. In most parts of the Gulf region, solar and wind energy sources are abundantly available. However, attempts to harness those resources are very limited. Furthermore, in this review report, innovative areas of advanced research (such as bioenergy, biomass) were proposed for the Gulf region to extract those resources at a higher magnitude to generate surplus power generation. Overall, this report clearly depicts the current scenario, current power demand, currently installed capacities, and the future strategies of power production from renewable power sources (viz., solar, wind, tidal, biomass, and bioenergy) in each and every part of the Gulf region.

This paper gives a review of energy scenario in India and other countries. Today’s demand of the world is to minimize greenhouse gas emissions, during the production of electricity. Henceforth over the world, the production of electrical power is changing by introducing abundantly available renewable energy sources like sun and wind. But, because of the intermittent nature of sustainable power sources, the electrical power network faces many problems, during the transmission and distribution of electricity. For resolving these issues, Electrical Energy Storage (EES) is acknowledged as supporting technology. This paper discusses about the world electrical energy scenario with top renowned developed countries in power generation and consumption. Contribution of traditional power sources changed after the introduction of renewable energy sources like sun and wind. Worldwide Agencies are formed like International Energy Agency (IEA), The Central Intelligence Agency, (CIS) etc. The main aim of these agencies is to provide reliable, affordable and clean energy. This paper will discuss about the regulatory authority and government policies/incentives taken by different countries.  At the end of this paper, author focuses on obstacles in implementation, development and benefits of renewable energy.

Wind Power Plants

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.

Sustainable Power

A non-sustainable wellspring of energy is for the most part non-plentiful in nature and can be utilized until they exist in plenitude. As and when the acknowledgment of the decrease of the bountiful assets and natural risks hit, an auxiliary idea of use of non-pollutable-sustainable power sources shows up into place. Different vulnerabilities as for the plan and supplies of a vehicle emerge with less or weakened association of the sustainable assets. A few vulnerabilities will emerge from the capital venture part and extents from the general population and private segments. Another challenge is the contribution of the innovation to travel the flow ordinary vehicles to electrical vehicles (EV) and to coordinate the renewable energy sources (RES), for example, wind-vitality, sunlight-based photovoltaics, and differing assortments of bio-energies to constantly work according to the prerequisite to reduce greenhouse gas (GHG). This chapter deals with the integration and charging challenges and strategies, coordination of vehicles, demand integration, and solutions to them.

Realisation of “Smart city” concept is connected with introduction of activities as to increase in energy efficiency and resource saving in the area of electric utility industry, including for the account of applying renewable energy sources (RES). Introduction of concept elements is economically justified not only in big megapolises, but in minor residential areas, as well. Notwithstanding the growth in power production with the employment of sun and wind technologies, the share of RES-based power generating plants in Russia, remains inconsiderable and amounts to approximately 0.1% of the total registered output of country’s power sources. Development of this perspective sphere is mainly carried out in those Russian regions where diesel fuel is used at very high potential capacities of the sun and wind power. Projects as to RES development in Russia are economically substantiated for isolated power-engineering systems, their introduction allows to cut consumption rate of expensive diesel fuel which is environmentally unfriendly. The estimates as referred herein, evidence a necessity to substitute elements of power-generating equipment of diesel-powered plants with solar-power farms. Development of renewable energy-generating industry in the country must be facilitated, by accelerated introduction of this resource in the regions with autonomous power-supply, where RES provides a fairly good economic effect.
