ABSTRACT
Article history:
To compare the different result of optimization of a hybrid energy system.
hybrid renewable energy system (HRES) is the combination of renewable and non-renewable sources which is playing a very important role for rural area electrification when grid extension is not possible or excessively Non renewable sources like diesel power generator .
are used in a HRES for backup when renewable energy supply is not sufficient.
While the HRES is very important due to the smallest natural and physical contact compared to non renewable sources, this work proposed a comparison outcome with the help of different component by using HOMER software and get best optimize result for the model.
This paper presents a wide-ranging review of various aspects of HRES.
This paper discusses study, best sizing, and model, organize aspect and reliability issue.

INTRODUCTION
Electricity generation through renewable sources in a very important topic for research now days.
the reduction of fossil fuels and the knowledge of ecological humiliation is the main reason for increasing use of renewable energy in todayAos scenario, to reduce the effect of green house gases it is very important to develop of a HRES system in rural area .
Use of non renewable sources alone can be a very expensive process so to reduce the cost of electricity generation we can also use the renewable sources.
They are cheap and easily available for generation.
The main apparatus of the HES mainly is renewable power generator as a primary (AC/DC source.
, non-renewable generator as a backup system(AC/DC source.
, power conditioning unit, battery system, load (AC/DC) and sometimes it is grid connected while some time stand alone .
A general HRES configuration has been shown in Figure 1.
HOMER (Hybrid Optimization of Multiple Energy Resource.
is the international set in small grid software, based on decades of listen to the desires of user in the order of the world with knowledge in designing and arrange small grids and transmitted power system that can contain a grouping of nonconventional energy sources, storage, and conventional generation either it is through a local generator or a power grid.
Homer system used to reduce the dependency upon other conventional sources .
It used to simplify the designing task of the hybrid model, and optimization and evaluation of the economical and scientific option of a highest amount of options like machinery expenses, electric load, and power supply accessibility whether stand alone and grid connected.
HOMER basically designed for rural community electrification and now it is licensed to HOMER Energy.
Objective Oriented Project Plannin.
of a hybrid renewable energy system can be used to develop a novel approach of optimization .

Hybrid energy system component STUDY AREA Either the government companies are not able to set positive infrastructure for electricity in hilly areas of Uttarakhand because of transportation difficulties.
RTI query by Dehradun-based activist Ajay Kumar reveals this information through investigation.
that More than 76 villages of Uttarakhand are not electrified yet .
Amazingly, two district of Uttrakhand.
Uttarkashi and Pithoragarh divide global border with Nepal and China, have a mass of village unelectrified.

LOAD ASSESSMENT
Dehradun block has adequate sunshine as a natural resource.
it has moderate wind speeds while biomass available in great quantity as the animal population is much greater in this area and other parts of Data collected by the survey and the demand of energy is separated into five main category .
domestic load .
commercial load .
agriculture/irrigation load .
school load .
medical centers.
Domestic load consists of light, television set, fans, and radio system.
Commercial load include power for shops, community centre, street lights while agriculture load includes water pump, irrigation pump, well, fodder machine.
Medical centre load consist.
CFL, refrigerator, fans, while school load consist of CFL, ceiling fan, desktop, television Table 2 shows types of load for different section.
In this section year is divided into two segment of 6-6 month namely summer and winter from May to October and November to April respectively.
Different load profiles shown in Figure 2.

The optimization and simulation shows that on the base of reasonable COE and NPC, i.
with the entire four components we get best alternative but meet maximum consistency.
I model has the maximum renewable incursion II model consists of SPV/ biogas but no diesel/ battery has lowest NPC.
But there is no back up in the If somehow any renewable source are not present than we will not able to get electricity.
With the comparison of model 1 it reduce the initial cost But meet higher COE and NPC.
In i model without diesel generator has same problem as II model In IV model without battery does not have any storage system for excessive battery.
Which will increase operating cost so NPC and COE also increase REFERENCES
