Renewable Energy power systems is accessible in varied resources , followed by numerous technologies. It is noticied that there are two types technologies which are used for such systems one which can be displaceable and the another which is non- displaceable such as wind and solar PV technologies . In that system operators can hold back output but cannot raise it if the wind or solar resource is unavailable. Thus for wind and solar PV technologies, it faced challenges to power system operators. It become uncertain for output generation when it owes to maintenance of reliability of the system . For example wind energy required important operational challenges rising , including restriction from transmission and minimum generation limitation . Due to uncertainty of output generation certain problem arises such as relatively less speedy slope in wind generation due to passage of huge trail storm & requirement of operational reserves. No doubt , electricity demand also varies timely but its actions is usually well understood from decades of practice and the urbanized capacity to predict load with rational accurateness a day in advance. Thus there is need to proper study & assessment for REPS ( Renewable Energy Power System ) . Thus it is often suggested that improved operating procedures and strategies are desirable and should be take up to include the uniqueness of changeable generation. This will help to know technical feasibility to generate power with the help of wind and solar energy .

 

RE Futures discover several equipped proposition  of very high levels of renewable generation . Typically, transmission of the energy is a challenging and lengthy process. Thus there is need proactive planning looking in to future prospects of in order to persuade long term goals rewable energy penetration and its utilization as a system. For example:-

  • Maintaining system consistency
  • Ensuring ample active power transmit ability
  • Economically reasonable
  • As long as , right to use the most cost – valuable renewable resources
  • Stimulating transportation
  • Supporting efficient power markets by lessening obstruction
  • Preparation for future transmission passage requirements, not just those straight away evident.
  • Bearing in mind all alternative along with extra-high-voltage AC & DC, and machinery    progress like superconductors.
  • By making sure that non-wire alternatives are completely considered for eg: efficiency and locally   dispersed production.
  • As much as possible minimizing impacts on native population, animals , plants overall environment such as reducing green house gases emission , impacts of harmful pollutants etc.

Emphasis should be given to the benefits from the uses of power system to society than the cost incurred in order to achieve goals of using Renewable power energy systems.

Along with transmission, operational feasibility is also required like efficient markets.

 

Moreover in order to improve the forecasting of wind and solar energy there is need to develop interconnections between the close by and far off regions . Increment in the use of stored options.

 

RE Futures also lie at the hourly replication level which can be examine with the help of case study , in order to know that the system can meet predictable heaps with high levels of renewable electricity & its generation. Importantly  investigation of system reliability for huge renewable generations can be done by knowing the time & analysis the power flow of AC . Moreover along with these criteria the study and research needs to done in details infringing the pros and cons of it . Such as quantitative impacts & the suggestions basis on these impacts for power generation.

 

REPE needs to be studied & fabricate planning issues from transmission & generation of electricity power system by using renewable energy up to 80 %. A standard production model set up on the bases of observation made on the level of transmissions , the model execute economic unit assurance and economic transmit, founded on an optimization that assemble load and hold back requirement at minimum cost, focus on to a range of limitations on the system. A reliable operating system in such a model should well considered two aspects i.e data development and model development.

-Data Development

obtain additional comprehensive data on the output of variations and renewable resources to a large way and the connection of these resources with load. Data must be received from year to year as every time the technology varied & thus can generate good statistics

– Model Development

Operational tools and models should be planned & developed in such a way that with less cost  more penetration can be generated by using renewable energy . It should also address technical and institutional issues so that timely scheduling can be done in order to access market flexibility. Then researching the market changes from time to time so that it can deal with close to zero margin.

Moreover analysis of bulk power and alternative models can also be explored.
