Micro-hydro power is a type of Hydro electric power that typically produced up to 100 kW of electricity using the natural flow of water. These type of power plant can provide power to an isolated home or a small community. Micro- hydro system complement solar energy because in many areas in winter the water flow is maximum and solar energy is minimum.   In such areas micro-hydro power is used along with photo voltaic solar energy.

2. INTRODUCTION
 In modern world, people are more concerned with uninterrupted and frequent power
supply. In conjuncture to this, the report presents a proposal to maintain the voltage
and frequency to a fixed value in order to have a good quality of power supply. The
process of controlling the voltage and active power in a power system is called as
Load Frequency Control. The soul of this proposal is to maintain frequency during
load changes and also tie line power interchanges. This proposal is based in order to
reduce the steady state error.
 The complexity has been increased by use of different type of power sources in
modern power systems. Renewable energy sources are commonly used as an
alternate source of energy in present time.
 The integrated renewable energy scheme which consist PV, micro hydro and fuel cell
system as an energy storage scheme is considered a bright option to overcome the
nonrenewable sources like coal, gas and fuel. There are some technical challenges
caused by renewable energy sources. These problems are of maintaining and
protecting of the RESs, contributing in the system voltage and frequency regulation.

3. Micro Hydro Power System
 Micro-hydro power is a type of Hydro electric power that typically produced
up to 100 kW of electricity using the natural flow of water.
 These type of power plant can provide power to an isolated home or a small
community. Micro- hydro system complement solar energy because in many
areas in winter the water flow is maximum and solar energy is minimum.
 In such areas micro-hydro power is used along with photo voltaic solar
energy.

5. Diesel Engine Generator
 Diesel Generators are used to generate
electricity in situations of bad power
supply or power cuts.
 Diesel Generators are used in homes,
factories, industrial locations, workplace,
warehouses, construction sites to protect
your life from the hazards of power
blackouts.
 Diesel generators are available in different
functions and sizes depending on their
requirement.
 Diesel generators are fantastic value
additions to any home and business so as
to keep complete track during power cuts

6. Fuel Cell
 A fuel cell is an electrochemical conversion device.
 A fuel cell is made up of a fuel and an oxidant.
 A fuel cell is not a battery. A fuel cell is an open system. Batteries, in
contrast, are considered a closed system.

8. What is Fuzzy Logic?
 Definition of fuzzy:
Fuzzy- “not clear , distinct , or precise; blurred”
 Definition of Fuzzy Logic:
A form of knowledge representation suitable for notions that cannot be
defined precisely, but which depend upon their contexts.
 Fuzzy logic is a form of many-valued logic; it deals with reasoning that is
approximate rather than fixed and exact. In contrast with traditional logic
theory, where binary sets have two-valued logic: true or false, fuzzy logic
variables may have a truth value that ranges in degree between 0 and 1
 Fuzzy logic has been extended to handle the concept of partial truth, where
the truth value may range between completely true and completely
false. Furthermore, when linguistic variables are used, these degrees may be
managed by specific functions.
