Abstract: Modern study about utilizing energy from renewable energy sources was stimulus due to emerging oil crisis in older days due to uncontrolled use of conventional energy sources. Renewable Power Generation from wind and solar energy has become a significant proportion for the overall power generation in the grid. High penetration of Renewable Power Generation (RPG’s) effectreliable operation of bulk power system due to fluctuation of frequency and voltage of the network. The main objectives of high penetration of Renewable Power Generations in distribution system are Regulation of voltage, Mitigating voltage fluctuations due to flickers and Frequency control. The design and control of voltage regulation system using smart loads (SL’s) under large penetration of renewable energy system in distribution level is to be studied with the help of FACT devices like Static Compensator (STATCOM) and It is one of the fast active devices with accurate voltage regulation capability and most importantly for the sensitive/critical loads. Electric spring (ES) is proposed as compelling technique for guideline of framework voltage under fluctuating RPG's with next to no guide of correspondence framework [1]. It is a converter-based framework with self-commutated switches in span design, which is associated with non-basic burdens in series to go about as savvy load. These Smart Loads are controlled to direct voltage across basic burdens and hence partaking popular side administration. Expanded entrance of RPG’s, basically factor speed wind energy transformation framework is having impact on voltage and power quality [1][2]. In this paper, A contextual analysis of impact of variable speed wind energy framework on voltage is completed and which is demonstrated with fluctuating breeze speed. Execution examination of keen burdens are to be contrasted and existing receptive power compensator burdens and Improvement in voltage profile on test feeder is directed on a 3 Bus system and 15 Bus system.

Renewable Power Generation

 Nowadays, renewable power generation has transformed to an important substitute to conventional power generation and severe the energy crisis of present-days. Apace thriving manufacturing division is swelling day by day and their energy marketability is also advancing. The potential of renewable energy is inclining every year, so the integration pace of renewable power in the system has inclined. However, influenced by meteorological and environmental terms and conditions the efficiency of renewable power generation often switches randomly, which disturbs the balance of power and voltage tenacity of power system. Also power precent is a giant contributor in green house gas emissions. United nation 17 sustainable development goals encourage enhancing the capability of power generation by utilizing industrial revolution 4.0 features. Industrial revolution 4.0 main factors are eco friendly and free gas emissions energy. Due to the renewable energy regulation introduced by the government under Alternative Energy Development Board to generate electricity from natural resources rather than fossil fuel. In this frame work industrial revolution 4.0 facilitate for extensive integration of renewable power into the network which is a massive task for power system operators and also for renewable energy farms to dispatch the power and taking critical actions. Industrial revolution 4.0 provides different pillars to overcome these issues likewise interoperability connects machine, objects and humans through internet of things to make smart grids. Uncertainty is the biggest challenge in renewable energy which can’t be eliminated but it can be manageable by virtualization. Through cyber physical system, computational proficiency and physical assets are interconnected for transformation advancement in the system, smart decision acquire to form a reliable and accurate data.

Autonomous Power Systems

The urgency of developing renewable power generation in Russia is associated with the presence of a large number of regions with a low degree of electrification. More than two-thirds of the territory of Russia is located in the area of decentralized power supply, where the main source of energy is imported diesel fuel or associated gas from local fields. At present, one of the directions for the development of renewable power generation in Russia is the implementation of a hybrid power supply system for autonomous power systems of remote regions. However, along with the possibility of using renewable energy sources, it is important for such regions to generate heat from co-generation of diesel power plants, since there is an urgent problem of heat supply for remote regions, especially located in the Far North of Russia. This article presents an analysis of the influence of using renewable energy sources in autonomous power systems on co-generation of diesel power plants.

Market Requirements

Market requirements for the gas turbine business have significantly changed in the last years due to a stronger demand for lifecycle cost optimization and the increased share of renewable energy. Gas turbine technology development focus must be adapted accordingly. The need for increased efficiency throughout the operation range, particularly at part load, requires more accurate and faster design methods and prediction capabilities. At the same time, technologies must be developed and validated to increased flexibility in many areas, including unlimited operation range (without aerodynamic, mechanical or emission constraints), fuel types and composition, and faster ramp up rates (despite the increased thermal stress to gas turbine components) to stabilize the grid and to compensate for intermittent renewable power generation. Further lifecycle optimization counts on new technologies in reconditioning, lifetime monitoring and improved lifetime prediction. This paper provides an overview of the recent research and development activities, the approach to bring them into a product and the resulting trend in Alstom gas turbine technologies.

Renewable Power Generation

Electricity is a pre-requisite for technological progress and economy growth. Thailand has been facing an electric energy crisis in inadequate electricity generation capacity compared with the demand. It is essential to replace the conventional energy (e.g. fossil fuels) with renewable energy resources, particularly biomass that can play a major role to meet the electricity demand. A modified deming PDCA management has been proposed for power generation. The objective of this study is to evaluate the future electricity consumption as well as to explore the current state of renewable energy potential in Nakhonratchasima Province, Thailand. The results show an electricity energy potential of from agricultural residues, livestock manure and solar energy resources. It is indicated that each these resources can supply the electricity demand excesses. The selection of renewable power generation is mainly driven by the installation cost and the availability of renewable energy resources. The power plant from livestock manures resources is found to be the most promising because its power plant installation requires lower investment in this study.

The Impact

A tanulmány arra keresi a választ, hogy a megújuló alapú áramtermelők támogatása csökkentőleg hathat- e a villamos energia nagykereskedelmi és kiskereskedelmi árára. Ez utóbbi tartalmazza a megújulók támogatásának összegét is. Számos elméleti cikk rámutatott arra, hogy nemcsak a nagykereskedelmi árak, hanem a kiskereskedelmi villamosenergia-árak is csökkenhetnek a drágább, megújuló alapú áramtermelők támogatása révén. A tanulmány során egy villamosenergia-piacokat szimuláló modell segítségével modellezi a szerző, hogy a különböző mennyiségű szélerőművi és fotovoltaikus kapacitás támogatása hogyan hat a magyarországi nagykereskedelmi és kiskereskedelmi árakra. _____ Impact of the Hungarian renewable based power generation on electricity price The aim of this paper is to answer the question whether the support of renewable power generation could decrease the wholesale and retail electricity prices. The latter one includes the support of renewables. Several studies point out that not only the wholesale, but the retail electricity prices could decrease when supporting the more expensive, renewable power generation. A model, which simulates the electricity markets, is used in order to analyse the impact of different level of wind and photo voltaic power generator support fee on Hungarian wholesale and retail electricity prices.
