India has over 2.5 GW of installed solar photovoltaic capacity as of May 2014. While India added only 916 MW of new solar installations in 2013, it still ranked sixth globally for solar capacity additions that year. Government policies have been the primary driver of India's solar energy sector, but the market is gradually shifting from incentive-driven to price-parity driven as solar plants without power purchase agreements from utilities are contributing more capacity. The announcements of new state-level solar policies and allocations under the National Solar Mission's Phase 2 have increased excitement for solar development in India.

3. Tariffs apply within the licensee's area of operation. Taxes and surcharges are extra as decided by the state government.
4. Provisions for unauthorized resale, delayed bill payment penalties, load limit exemptions, and incentive for timely/advance
The Availability Tariff mechanism in India separates fixed and variable power plant costs. It provides incentives for power plants to increase availability during peak hours and back down during off-peak hours. This helps meet more consumer load when needed and reduces excess generation when not. The mechanism also defines beneficiaries' shares of central plant capacity and schedules to bring discipline to regional grids previously operating in an undisciplined manner. It benefits all constituents by improving grid parameters, encouraging lower-cost generation, and establishing mechanisms for additional power sources and trading.

Implementation of ac induction motor control using constant vhz principle and...eSAT Journals
Abstract
This paper presents the hardware implementation of V/f control of induction motor using sine wave PWM method. Because of its
simplicity, the V/F control also called as the scalar control, is the most widely used speed control method in the industrial
applications. In this method the ratio between stator voltage to frequency is maintained constant so that the stator flux is
maintained constant. As the stator flux is maintained constant, the torque developed by the motor depends only on the slip speed
and is independent of the supply frequency. Thus we can control the speed and torque of induction motor by simply controlling the
slip speed of induction motor. The complete control is achieved with the help of TMS320F28027 Development Board. One of the
basic requirements of this scheme is the PWM inverter. The gating signals are generated using sine wave PWM technique.
Implementation issues such as PWM signal generation, ramp control, v/f control, inverter design are discussed. The results are
discussed based on the various waveforms.

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Deviation Settlement Mechanism and Related Matters
CERC Regulation 2014
CERC on 17.02.2014 has replaced the UI regulation 2009 with Deviation settlement mechanism regulation 2014 in
order to strengthen the grid and improve grid stability. This step was taken to ensure that situations of grid failure
like that of 30th
& 31st
July will not happen again. The grid failure has presented a case where some state were using
the UI as a trading platform, during the grid failure states like Haryana, U.P were overdrawing heavily whereas states
like Rajasthan & MP were under drawing from their schedule resulting in frequency varying in the specified range
and at the same time making the grid unstable thus resulting in grid failure.
With this regulation CERC has implemented volume limit for buyer and seller depending on their approved schedule,
range of frequency has tighten, charges for the unscheduled interchange or deviation has increased to ensure a
better demand predictability by states and to avoid UI as a trading platform.
Deviation & Settlement Mechanism will definitely improve the grid discipline and will help the state to initiate
forecasting of demand and schedule in more accurate and stringent manner. Various provisions made in the
regulation such as volume limits, additional charges etc will force the state to procure power through bilateral route
or on day ahead basis which surely help in fund flow and eventually improve the position of power sector.
A summary of the deviation settlement mechanism and its comparison with the previous prevailing UI regulation is
provided below.
1. Title & Commencement: Deviation settlement mechanism & related matters regulation 2014, came into force on
17.02.2014.
2. Reference Regulation:
a. Grant of connectivity, LTOA & MTOA in interstate transmission regulation 2009.
b. Interface Meters (Installation & operation of meters) regulation 2006.
c. Open Access in interstate transmission regulation 2008.
3. Objective of the regulation is to enhance grid discipline & grid security.
4. Applicable on Inter-state transmission of electricity.
5. Charges receivable for under drawl by buyer and over injection by seller, while charges are payable for over drawl
by buyer and under injection by seller.
6. Provisions made in regulation:
a. Redefined frequency range and rates.
b. Volume limits and deviation limits for generator and buyer
c. Cap Rate applicable
d. Charges & Additional Charges
e. Methodology for calculation of deviation charges.
7. Charges and conditions applicable:
a. Charges for each step increment of frequency for each 0.01 Hz step is now equivalent to increment
of 35.60 Paise/unit in the frequency range of 50.05-50.00 Hz & 20.84 Paise/unit in frequency range
between 50.00Hz to not below 49.70 Hz, resulting in charges at 50.05Hz @ 0.00 Paise/unit, at
50.04Hz @ 35.60 till 50.00 Hz @ 178 Paise/unit and then from 49.99Hz onwards charges will
increase at a rate of 20.84 till 49.7Hz @ 824.04 Paise/unit. In UI regulation 2009 charges for each
step of frequency for each 0.02 Hz was equivalent to 16.50 Paise/Unit from 50.20Hz till 50.02Hz, i.e
charges were at 50.20Hz @ 0.00 Paise/unit & at 50.02 @ 148.50 Paise/Unit, and then from 50.00Hz
2. Strengthening of Indian Grid
Mohit Kathel indianpowerindutry.com
onwards each step increment was equivalent to Rs. 28.12 Paise/Unit i.e. charges at 50.00Hz @
165.00 Paise/Kwh till 49.5Hz @ 900.00 Paise/Unit.
b. Cap Rates are redefined in the present regulation, now the cap rate for generating stations using fuel
which comes under APM is reduced to 303.04 Paise/Kwh from 421.50 paise/Kwh for higher or lower
injection than the scheduled generation. Also, now there is no cap rate on generating stations which
are regulated by consumer and are using Gas as fuel under APM.
c. Charges for over injection by seller and under drawl by buyer in excess of 12% of schedule or 150
MW whichever is less shall be 0. Earlier over injection upto 120% of schedule is allowed on the
corresponding frequency rate and in excess of 120% there was a cap rate of 450.00 Paise/Unit,
although it was subject to 105% of declared capacity of plant in a time block and 101% of capacity of
plant in a day.
d. Earlier if the injection of plant increases beyond 105% of its declared capacity in a time block or
101% of declared capacity in a day then charges for such injection will be charged at a rate of 165
Paise/unit. In the present regulation there are no such rules applicable on power plants.
e. Clause for infirm injection before COD of generating unit is almost similar to that of UI regulation
2009, There is no volume drawl or injection limit on generating station although there is a cap rate
on injection which is subject to the fuel used, for APM gas cap rate has increased from earlier charge
of 2.60 Rs/Unit to 5.64 Rs/Unit.
f. Volume Limits have been implemented in the present regulation, earlier there wasn’t any volume
limits on the overall injection or drawl, although based upon different UI volume, charges
corresponding to percentage of prevailing UI charges and Cap Rates were there.
g. Earlier for over drawal when frequency is below 49.80Hz, additional charges were there. Now there
are volume limits too which are 12% of schedule or 150 MW whichever is less. Also, now additional
charges are levied based on the deviation from schedule and not upon the frequency range as was
earlier.
In the present regulation no under injection of electricity by a seller shall be permissible when grid frequency is
"below 49.70 Hz" and no over injection of electricity by a seller shall be permissible when grid frequency is "50.10
Hz and above.
However, additional charges shall be levied now depending on the deviation from schedule more than the allowed
limits i.e. 12% or 150 MW whichever is less and also depends upon the frequency. Different charges are defined for
the frequency range 49.70 Hz and above and below 49.70Hz of frequency.
1. When grid frequency is 49.70Hz and above
a. When 12% is lesser or equal to 150 MW
b. When 12% is more or equal to 150 MW
2. When grid frequency is below 49.7 Hz
Each of the cases will apply for over drawal by a buyer and under injection by a seller when the actual
drawl/injection is higher than the specified limits.
For Over-Drawal by a buyer when frequency is 49.70 Hz or above
When 12%<=150MW When 12% >= 150 MW Additional Charges
a. 12%-15% 150MW to 200MW
+20% charges of deviation charge
corresponding to average grid
frequency of the time block.
b. 15%-20% 200 MW to 250 MW +40% charges of deviation charge

corresponding to average grid
frequency of the time block.
c. 20% & Above 250 MW and above
+100% charges of deviation charge
corresponding to average grid
frequency of the time block.
For Under-Injection by a seller when frequency is 49.70 Hz or above
When 12%<=150MW When 12% >= 150 MW Additional Charges
a. 12%-15% 150MW to 200MW
+20% charges of deviation charge
corresponding to average grid
frequency of the time block.
b. 15%-20% 200 MW to 250 MW
+40% charges of deviation charge
corresponding to average grid
frequency of the time block.
c. 20% & Above 250 MW and above
+100% charges of deviation charge
corresponding to average grid
frequency of the time block.
For Under-Injection by a seller using fuel coal/gas/lignite under APM & when frequency is 49.70 Hz or above
When 12%<=150MW When 12% >= 150 MW Additional Charges
a. 12%-15% 150MW to 200MW
+20% of 303.04 Paise/Unit or
deviation charge corresponding to
average grid frequency of the time
block whichever is less.
b. 15%-20% 200 MW to 250 MW
+40% of 303.04 Paise/Unit or
deviation charge corresponding to
average grid frequency of the time
block whichever is less.
c. 20% & Above 250 MW and above
+100% of 303.04 Paise/Unit or
deviation charge corresponding to
average grid frequency of the time
block whichever is less.
When grid the frequency is below 49.70Hz, additional charges are levied for over drawal by a buyer or under-
injection by a seller and are equivalent to 100% of 824.04 Paise/unit i.e. 1648.08 Paise/unit for the deviation.
Similarly for generating station using coal/gas/lignite additional charges are equivalent to 100% of the cap rate
(303.04 paise/kwh).
Provided:
1. Additional charge for deviation also be levied for over-injection or under-drawal when grid frequency is
50.10Hz or above at the rates equivalent to charges of deviation corresponding to the grid frequency of
“below 50.01 Hz but not below 50.0 Hz” i.e. 178.00 Paise/unit.
2. No additional charges are levied on generating station prior to COD of unit.
3. These charges and regulation are subject to change depending upon the order, rules, amendments or
regulation of CERC.
