Tariff
The electrical energy produced by a power
station is delivered to a large number of
consumers. The consumers can be per-
suaded to use electrical energy if it is sold at rea-
sonable rates. The tariff i.e., the rate at which
electrical energy is sold naturally becomes atten-
tion inviting for electric supply company. The
supply company has to ensure that the tariff is
such that it not only recovers the total cost of
producing electrical energy but also earns profit
on the capital investment. However, the profit
must be marginal particularly for a country like
India where electric supply companies come un-
der public sector and are always subject to criti-
cism. In this chapter, we shall deal with various
types of tariff with special references to their ad-
vantages and disadvantages.
Abstract The demand for high quality electricity and growing electricity consumption has been caused by increasing electrification of daily life causes and the rising number of sensitive or critical loads. Due to the rapid increase in global energy consumption and the diminishing of fossil fuels, the customer demand for new generation capacities and efficient energy production, delivery and utilization keeps rising. The micro grid concept has the potential to solve major problems arising from large penetration of distributed generation in distribution systems. A proper control strategy should be implemented for a successful operation of a micro grid . Different load models can be simulated and analyzed using MATLAB and PSCAD software. In this paper, the work done in the field of Micro Grid has been reviewed. Keywords: DER, MG, PCC, PV, VSI.

Successful implementation of DR program is possible if the users participates into it willingly without compromising with their comfortable life style
DR program does not ensure same amount of benefit for all the participating players i.e, some may be incentivized whwre as some can receive penality.
The employment of DR relies on the reliable,robust and secure communication system.
Choice of efficient energy price structure is the main key factor to attract the users towards DR programs.
The project involves determining real time electricity charges incurred by the residential consumers. The smart grid integrated with residential PV systems was modeled in Simulink to determine demand response in dynamic pricing environment. Based on the load demand, electricity charges were calculated and compared with flat rate charges to highlight cost savings.

Demand side management
It is also called as energy demand management
The modification of consumer demand for energy through various methods such as financial incentive and education is termed as demand side management.
Héloïse Hoyos, Senior consultant at N-SIDE, gave a presentation about how to valorize your energy flexibility during the Energy Flexibility Forum organised by Solar Plaza on June 11-12
Distributed energy resources (DERs) can provide net benefits to the electric system (e.g., congestion relief) and broader society (e.g., emission reductions). However, despite these advantages, the deployment of high penetrations of DER has proved challenging. Against this backdrop, the electric utility is often singled out as a fundamental barrier to deployment of DER assets. To overcome the perceived electric utility shortcomings, many stakeholders conclude that a completely new model is needed for the electric industry.
ScottMadden disagrees with this assessment and instead believes electric utilities maintain natural advantages that can be leveraged to deploy renewables and DER assets as well or better than some models being offered. In our 51st Phase II Roadmap, ScottMadden proposes leveraging the natural advantages of the electric utility in order to accelerate the deployment and penetration of DER assets.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Introduction to DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
6. • Demand Side Management was introduced
publicly by Electric Power Research Institute
(EPRI) in the 1980s.
• Nowadays, DSM technologies become
increasingly feasible due to the integration of
information and communications technology and
power system, resulting in a new term: Smart
Grid.
• Definition - DSM (Demand Side Management) is
the 'Scientific control of usage and demand of
Electricity, for achieving better load factor and
economy, by the Licensee/Supplier'.

Why DSM ……?
Renewable Energy Sources Unit III * Final Part Dr. BNP
9. 1. Energy efficiency-Using less power to perform
the same tasks.
2. Demand Response-Any reactive or preventative
method to reduce, flatten or shift peak demand.
3. Dynamic Demand-Advance or delay appliance
operating cycles by a few seconds to increase
the Diversity factor of the set of loads. It would
be unnoticeable to the end user.

Benefits of DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
13. • DSM is a mechanism to influence customer’s
CAPABILITY and WILLINGNESS to reduce
electricity consumption.
• DSM is an utility program aiming to fine-tune
consumer’s energy consumption pattern,
according to the utility’s energy production and
distribution capacity.
• Demand-side management(DSM) programs
consist of the planning, implementing and
monitoring activities of electric utility that are
designed to encourage consumers to modify their
level and pattern of electricity usage.
13
Concept of DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
15. • To charge higher prices during Peak Hours
• Improving the efficiency of various end uses
by using energy efficient appliances, better
house keeping and reducing energy leakages.
This is important for agriculture where energy
efficiency is very low (30-50%)
• Promoting use of Energy Efficient
Technologies and addressing Aggregate
Technical and Commercial (AT&C) Losses
15
How to Perform DSM …..?
Renewable Energy Sources Unit III * Final Part Dr. BNP
16. 1. Load management programmes: Redistribute
energy demand to spread it more evenly throughout the day,
e.g., load shifting programmes (reducing loads during periods
of peak demand and shifting these loads to less critical
periods), and time-of-use rates (charging more for electricity
during periods of peak demand).
2. Conservation programmes: Reduce energy use, e.g.,
programmes to improve the efficiency of equipment,
buildings, and industrial processes.
3. Strategic load growth programmes: Increase
energy use during some periods, e.g., programmes that
encourage cost-effective electrical technologies that operate
primarily during periods of low electricity demand.
16
DSM Activities
Renewable Energy Sources Unit III * Final Part Dr. BNP
17. 1. Develop end-use Demand forecasting
• Forecasting by end-use is an essential pre-
requisite for effective DSM planning and
implementation.
• Mid- and long-term forecasts of power demand
variations play a very important role in the
development of a DSM programme.
• Demand forecasting is an exercise that every
electricity-generating company should carry out
regularly in order to assess its future equipment
requirements.
17
Planning & Implementation of DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
18. 2. Undertake Load/ Market Research to identify end-use
patterns and market barriers
• To design effective DSM programmes it is important to
know how electricity is used and what barriers are
preventing customers from using efficient technologies.
• Load research should be undertaken to estimate load
curves for each sector or region, using local sub-metering,
customer bill analysis and customer surveys.
• Major areas of interest to DSM programmes include the
residential, commercial, industrial, and public utility
sectors.
• Market research is needed to understand the target
market, identify barriers and evaluate possible solutions.

Renewable Energy Sources Unit III * Final Part Dr. BNP
20. 3. Define load-shape objectives
20
Planning & Implementation of DSM
•The reduction of utility load,
more or less equally,
during all or most hours of the day
•Non traditional approaches to
load management
•The INCREASE of utility load
•Load-shape change which
refers to overall increase in sales
•The interruptible
agreements by
utility to alter
customer energy
consumption
on an as-needed basis
Renewable Energy Sources Unit III * Final Part Dr. BNP
21. 4. Identify target sectors, end-uses, and measures
• The collected information is normally useful in
determining a typical load curve for each end-
use.
• Find out load-curve management objectives
• Choose sectors and end-uses that account for the
largest power consumption and peak loads, or
will do so in the future.
• Select DSM measures which will have the largest
impact on peak demand and electricity use.
21
Planning & Implementation of DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
22. 5. Identify sources of financing
• In any DSM programme, financing is needed
for individual projects undertaken by
participants.
• Utilities may also require financing to cover
administrative costs and cost sharing
investments.
• Government/public fund is required.
22
Planning & Implementation of DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
23. 6. Review Cost Sharing and Viability Options
• Cost sharing in a DSM programme should try to
maximize viability for each partner (participant, utility,
and government).
• If current tariffs are below the marginal cost of new
power supply options, it is financially viable for the
utility to share in the cost of the efficient technology
and maximize participation in the programme.
• The wider the differences between tariffs, the higher
the utility investment can be, which in turn leads to a
higher participation rate.
23
Planning & Implementation of DSM
Renewable Energy Sources Unit III * Final Part Dr. BNP
24. 7. Programme Selection and Design
• Identifying a list of programmes for each
customer class.

• KVA means Kilo volt ampere. V*I*1000
• KVAR means Kilo Volt Ampere Reactive. V*I*Sinϕ*1000
• KW means Kilo Watt. V*I*Cosϕ*1000
• The power supplied by us is called apparent power (kVA). Apparent
power is broken down into active power (kW), and reactive power
(kVAR). Active power provides energy for motion, heat, light and
sound. Reactive power (inductive) is used to create magnetic fields
necessary to drive rotating equipment such as motors,
compressors, etc.
• Power factor = Active power (kW) X 100 / Apparent power (kVA)
• By installing capacitors, the reactive power component (kVAR) by
the Utility will decrease causing the apparent power component
(kVA) to decrease thereby improving the power factor.

and WILLINGNESS to reduce electricity
consumption
Renewable Energy Sources Unit III * Final Part Dr. BNP
80. DSM Program Design - Principles
• Systematic road-map for overcoming barriers faced by
customers in their goal of reducing electricity
consumption (and bills)
– BOTH in short-term and long-term
• Must be cost-effective – i.e. program costs must be
lower than benefits from program
• Ensure customer satisfaction
Renewable Energy Sources Unit III * Final Part Dr. BNP
81. Types of DSM Programs
• All three reduce energy consumption (kWh) and peak demand (kW), however, emphasis
differs
– Energy Efficiency – emphasis is on reducing overall energy
consumption and also peak demand over several years
– Peak Load Management– emphasis is on reducing peak
demand consistently over a season
– Demand Response – emphasis is on reducing peak demand
for short periods of time for a few days during the year
Renewable Energy Sources Unit III * Final Part Dr. BNP
82. Energy Efficiency
• Permanent energy (kWh) reduction
– Permanent peak demand (kW) reduction
• Size of impact is predictable
• No reduction or shift in customer value, comfort, or output
• Not dispatchable by distribution company
• Examples – rebates on efficient appliances, energy savings performance contracting,
etc.
Renewable Energy Sources Unit III * Final Part Dr. BNP
83. Peak Load Management
• Overall energy consumption likely to stay same
– Focus is on changing customer load profile
• Size of impact fixed
• Fixed duration (4 - 6 hours daily) demand (kW) reduction
• Change/transfer in customer value, comfort, or output
• Not dispatchable by distribution company
• Examples – tariffs for agricultural pumps
Renewable Energy Sources Unit III * Final Part Dr. BNP
84. Demand Response
• Overall energy consumption may vary based on customer load curtailment
strategy
– Focus is on changing customer load profile
• Size of impact may vary from event to event
• Small duration (15 min – 6 hours) demand (kW) reduction
• May involve a reduction in customer value, comfort, or output
• Dispatchable by distribution company
• Examples – “cycling” of air conditioners, critical peak pricing tariffs s
