• Data transmitted through gateway is stored & processed securely within the cloud
infrastructure using Big Data analytics
• End-user mobile apps will help end users to control & monitor their devices from
remote locations.
• IPv6 addresses are the backbone to the entire IoT ecosystem.
WHY SMART GRIDS?
• The basic structure of the electric power
grid has remained unchanged for many
years.
• Existing power generation infrastructure is
not able to keep pace with growing power
demand.
• The methods of power delivery to
consumers are outdated and inefficient.
• Global power industry is facing challenges.
• Current trends in energy supply and use are
unsustainable-economically,
environmentally and socially.
• The electric grid in its current state is falling
behind technological advancements and
energy demands.
• IEA Predict the overall energy use to double
by 2030.
• Most of the expansion will be powered by
growth in fossil fuels.
• We need to reduce emissions of CO2 and
other greenhouse gases by at least 60% by
2050, if we are to meet our emissions
reduction target.
SMART GRID V/S CONVENTIONAL POWER GRID:

• No Self Healing Vertical Structure
• Mostly one way communication
• Limited intelligence
WHAT DOES SMART GRID
IMPROVISE?
• Generation
• Transmission
• Distribution
• Customer participation
• Operations
• Markets
• Service Providers
SMART PHOTOVOLTAIC SYSTEM
ARCHITECTURE
• Internet of Things:- IoT is the chain of daily objects like electronics, software,
sensors, and connectivity which exchange data
• Microcontroller:- microcontroller process high-performance with Microchip pico
Power, Arduino, zig-bee, 8-bit AVR RISC(Reduced Instruction Set Computing)
• Wireless transceiver:- Nordic nRF24L01+ is highly integrated with ultra low power
(ULP) 2Mbps RF transceiver and IC for the 2.4GHz band.
• Current sensor:-Current sensor is used for measuring AC and/or DC current levels.
• Voltage Sensor:- voltage sensors all produce outputs as Amplitude Modulation,
Pulse Width Modulation or even Frequency Modulation.

TREND IN ILLUMINATION AND VOLTAGE
SHORT-TERM POWER FORECASTING MODEL
FOR PHOTOVOLTAIC PLANTS
• New model for short-term forecasting of electric energy production in a
photovoltaic (PV) plant. The model is called “HIstorical SImilar Mining” (HISIMI)
model.
• The economic reasons have driven the development of short-term power
forecasting models for wind farms or for relatively large grid-connected PV
plants.
• In the last decade, tens of short-term wind power forecasting models have been
described
WHAT IS EOOM?
All these innovations, which are gradually taking place, are needed to enable the
transition to a future CO2-neutral power system.
Equation-Based Object-Oriented Modelling(EOOM) methodologies and of the
Modelica language in this field. Modelica is an object-oriented, declarative, multi-
domain modeling language for component-oriented modeling of complex systems,.
Vanfrettietal and Zhangetal have already demonstrated that EOOM and Modelica
can be successfully employed for the modelling and simulation of power grids, also
validating their results against well-established domain-specific simulation tools.
FEATURES OF SMARTGRID MODELLING
FRAMEWORK
• Declarative modelling:- describe how a system behaves.
• Model/Solver separation:- first creates the model in a language that allows to
write equations, and then feeds this model to appropriate numerical solver.
• Multi-domain modelling:- use differential-algebraic equations for the basic
description of physical behavior.
• Multi-paradigm modelling:- they combine physical hardware of diverse nature.
• High-level modelling:- use abstract and high level modelling languages, leaving
the details of the coding in to actual simulation Code to software tools.
• Modularity and encapsulation:- model should be developed so as to be valid
whatever is later connected to its physical interface, as long as this makes physical
sense.
• Flexible level of detail:- devise symbolic and numeric manipulation procedures to
bring the model in a form which are well-suited.
• Large-scale Smart Grid modelling:- can feature possibly tens of thousands of
components.
• Use of open standards and tools:- using different tools that excel at a particular
analysis or simulation task starting from a common, tool-independent code base.
SMART GRID NETWORK:
WHAT DOES IT LOOK LIKE?

WHAT ARE MICRO GRIDS?
• A micro grid is a discrete energy system consisting of distributed energy sources
(including demand management, storage, and generation) and loads capable of
operating in parallel with, or independently from, the main power grid.
• The primary purpose is to ensure local, reliable, and affordable energy security for
urban and rural communities, while also providing solutions for commercial, industrial,
and federal government consumers.
• Micro grids perform dynamic control over energy sources, enabling autonomous and
automatic self-healing operations.
• a micro grid can operate independently of the larger grid and isolate it’s generation
nodes and power loads from disturbance without affecting the larger grid's integrity.
BENEFITS OF MICRO GRIDS
• Provides power quality, reliability, and security for end users and operators of the grid
• Enhances the integration of distributed and renewable energy sources
• Cost competitive and efficient
• 
Enables smart grid technology integration
• 
Locally controlled power quality
• Minimize carbon footprint and green house gas emissions by maximizing clean local
energy generation
• 
Increased customer (end-use) participation
MICRO GRID FOR INTEGRATION OF SEVERAL SOURCES AND
STORAGE
(A) AC MICRO-GRID (B) DC MICRO-GRID
THE SMART GRID IS MORE:
• Reliable
• Secure
• Economic
• Efficient
• Environmentally friendly
• Safe
CONTINUED…
• Enable active participation by consumers
• Accommodate all generation and storage options
• Enable new products, services, and markets
• Provide power quality for the digital economy
• Optimize asset utilization and operate efficiently
• Anticipate & respond to system disturbances (selfheal)
• Operate resiliently against attack and natural disaster
CONCLUSION
The Smart Grid will come from the application of intelligent energy technology to optimize the use of
generation resources and the delivery of power.
There are several key challenges that should be addressed before smart grid implementation like:
• Voltage stabilization
• Power management
• PQ management
• Failure Protection
• Grid integration
• Stability issues
• Islanded operation

FEATURES OF SMARTGRID MODELLING FRAMEWORK • Declarative modelling:- describe how a system behaves. • Model/Solver separation:- first creates the model in a language that allows to write equations, and then feeds this model to appropriate numerical solver. • Multi-domain modelling:- use differential-algebraic equations for the basic description of physical behavior. • Multi-paradigm modelling:- they combine physical hardware of diverse nature. • High-level modelling:- use abstract and high level modelling languages, leaving the details of the coding in to actual simulation Code to software tools.
  • 16. • Modularity and encapsulation:- model should be developed so as to be valid whatever is later connected to its physical interface, as long as this makes physical sense. • Flexible level of detail:- devise symbolic and numeric manipulation procedures to bring the model in a form which are well-suited. • Large-scale Smart Grid modelling:- can feature possibly tens of thousands of components. • Use of open standards and tools:- using different tools that excel at a particular analysis or simulation task starting from a common, tool-independent code base.

  • 21. WHAT ARE MICRO GRIDS? • A micro grid is a discrete energy system consisting of distributed energy sources (including demand management, storage, and generation) and loads capable of operating in parallel with, or independently from, the main power grid. • The primary purpose is to ensure local, reliable, and affordable energy security for urban and rural communities, while also providing solutions for commercial, industrial, and federal government consumers. • Micro grids perform dynamic control over energy sources, enabling autonomous and automatic self-healing operations. • a micro grid can operate independently of the larger grid and isolate it’s generation nodes and power loads from disturbance without affecting the larger grid's integrity.
  • 22. BENEFITS OF MICRO GRIDS • Provides power quality, reliability, and security for end users and operators of the grid • Enhances the integration of distributed and renewable energy sources • Cost competitive and efficient •  Enables smart grid technology integration •  Locally controlled power quality • Minimize carbon footprint and green house gas emissions by maximizing clean local energy generation •  Increased customer (end-use) participation

  • 25. CONTINUED… • Enable active participation by consumers • Accommodate all generation and storage options • Enable new products, services, and markets • Provide power quality for the digital economy • Optimize asset utilization and operate efficiently • Anticipate & respond to system disturbances (selfheal) • Operate resiliently against attack and natural disaster
  • 26. CONCLUSION The Smart Grid will come from the application of intelligent energy technology to optimize the use of generation resources and the delivery of power. There are several key challenges that should be addressed before smart grid implementation like: • Voltage stabilization • Power management • PQ management • Failure Protection • Grid integration • Stability issues • Islanded operation
