INTRODUCTIONINTRODUCTION As convention fossil fuel energy sources diminish As convention fossil fuel energy sources diminish and the

world’s environmental concern about acid deposition and global warming increases, renewable energy sources (solar, wind, tidal,biomass and geothermal etc) are attracting more attention as alternative energy sources.

Load shedding in many cities in India due to power Load shedding in many cities in India due to power shortage and shortage and

faults is a major problem for which there is no immediate faults is a major problem for which there is no immediate remedy in the near future since the gap between the remedy in the near future since the gap between the power demandand supply is increasing every year.power demandand supply is increasing every year.

Advantage of hybrid energy systems India has monsoon climate hence has enough potential of windenergy. Biomass energy is good option but it needs regular feeding continuously operate. Biomass with grid hybrid system is broadly used in sugar mill in India. In residential applications, biomass can be used for space heating or for cooking. Businesses and industry use biomass for several purposesincluding space heating, hot water heating, and electricity generation system to be more reliable and have low cost, power grid should be involve in the hybrid system All energy sources have an impact on the environment. Concerns aboutthe greenhouse effect and global warming, air pollution. energy security have led to increasing interest and more development in renewable energy sources such as solar, wind, geothermal, wave power and hydrogen.

fetures of hybrid systemsHybrid systems can address limitations in terms of fuel

flexibility, efficiency, reliability, emissions and / or economics.

Incorporating heat, power, and highly efficient devices (fuel

cells, advanced materials, cooling systems, etc.) can increase

overall efficiency .

conserve energy for a hybrid system when compared with

individual technologies.

Achieving higher reliability can be accomplished with

redundant technologies and/or energy storage.Hybrid systems can be designed to maximize the use ofrenewable. Resulting in a system with lower emissions than traditionalfossil-fueled technologies.

Hybrid Wind-Solar Energy SystemHybrid Wind-Solar Energy SystemThe common inherent drawback of wind

and photovoltaic systems are their intermittent natures that make them unreliable.

However, by combining these two intermittent sources and by incorporating maximum power point tracking (MPPT) algorithms, the system’s power transfer efficiency and reliability can be improved significantly.

Hybrid Renewable Energy SystemsHybrid Renewable Energy Systems On the other hand, the proposed renewable energy based system

helps in:

Decrease environmental pollution

Reduction of air emission

Energy saving Reduces production and purchase of fossil fuels

Abatement of global warming

CO2 and other green house gases are not produced

Socioeconomic development Develops employment opportunities in rural areas

Fuel supply diversity

Diversity of energy carriers and suppliers

Distributed power generation

Reduces requirement for transmission lines within the electricity grid

Challenges Challenges • Site dependence of renewable sources• While planning, designing and constructing a hybrid energy system, the problem

becomes complex through uncertain renewable supplies, load demand, non-linear characteristics of components

Site survey with long term data acquisition & forecasting

• Hybrid renewable energy system designConfiguration and sizing of the hybrid system components with the

objectives: Supplying the power reliably under varying atmospheric conditions Minimizing the total cost of the system Maximizing the system efficiency by efficient energy flow management

strategies

Optimization through simulation studies under real operating conditions for a reasonable tradeoff among conflicting design objectives

Market potentialMarket potential

India has a large potential for renewable energy (RE), an estimated aggregate of more than 100,000 MW. • Extendable to a generalized solution for any kind of stand-alone

site.

• Independent of continuous availability of the renewable source as well as grid power availability.

For any kind of critical load in stand-alone site
