Energy Optimization Portal
Energy
is an �online� resource in that it is produced and consumed simultaneously.
Any decision support system used by a participating organization in the power
market (be it a generating company, transmission company, distribution company,
system operator) need to be a fully integrated and online system to provide
maximum value to the user. EOP (Energy Optimization Portal) caters to this
critical requirement of utilities to have a fully integrated and online decision
support system that spans multiple functions, departments and locations.
The
core objective of EOP is to optimize the revenue of a utility by acting as an
online, real-time decision support system. All users in the energy chain
starting from the generating stations, transmission utilities, distribution
companies, market participants (such as IPPs and CPPs) are included in the broad
perspective of EOP
Modules
The
EOP is slit across modules and sub-modules. These are by no means, watertight
compartments. Information is freely shared across different modules. For
example, the ABT module may take as inputs the heat rate information provided by
the performance calculation module. The classification only provides a cohesive
and intuitive way of accessing information contained in the EOP application. A
brief description of these features across different modules is given below:
Plant
Management Module
Performance
Calculation module: deals with online performance calculation and efficiency
monitoring. Unit heat rate calculations, auxiliary equipments performance
calculations etc. are handled in this sub-module. Results are made available as
graphical and tabular reports. All calculations conform to relevant standards
such as Performance Test Codes from ASME. In addition, valuable optimization
guidance in terms of heat rate deviation and operator controllable losses is
also provided. Data validation is also handled by the performance calculation
module.
IAMS:
is the Intelligent Alarm Management System. This sub-module acts as an expert
system that identifies the root cause for critical alarms. In addition,
predictive analysis for slow varying process points is also provided by IAMS.
Statistical analysis of alarms and alarm grouping features are also available
through this module.
MOR:
Merit Order Rating sub-module deals with optimal load allocation of the station
demand across running units. This module is integrated with the ABT module and
can take the ninety six 15-minute dispatch schedule for the station as its
input. Optimization results are provided in graphical and tabular format to the
operator.
MMS:
Maintenance Management sub-module is a inventory management and maintenance
tracking solution tailored for power generating stations. Parts and spares
management as well as maintenance scheduling, optimization and tracking are the
key features of this module. Predictive maintenance through condition monitoring
for critical components as well as evaluating the effectiveness for a
maintenance activity is included in this module.
Soot
blowing optimization: assists the plant operators in optimal scheduling of
the soot blowing operation. This is done using online heat transfer rate
calculations. This approach assists the operators in striking the balance
between heat rate increase due to lack of soot blowing and steam loss due to
excessive soot blowing.
Energy
Market Module:
ABT
Module: This sub-module deals with Availability Based Tariff. Data from
different ABT compliant energy meters are downloaded and displayed through this
module. Trending and reports of this ABT data as well as calculation of UI rates
and charges under ABT specifications is handled by this module.
Scheduling:
While ABT is specific to the Indian power market, all other sub-modules in the
Energy Market module is applicable to any power market. Scheduling deals with
optimal scheduling and dispatch of power subject to generation and transmission
constraints. Thermal and hydro power scheduling are dealt with separately in
this sub-module.
Trading:
deals with optimization related to energy trading in a deregulated power market.
Open Access to Transmission facility under the ABT regime is handled in this
sub-module. Managing PPA (Power Purchase Agreements) as well as maximizing
revenue in short-term market opportunities is also handled through this module.
Tariff:
is a flexible tariff calculation engine to be used in the Energy Market module.
Energy tariff rates under different schemes can be specified here. Multiple
versions of the tariff structure can be maintained in the system. Based on data
downloaded from the ABT meters as well as information available from scheduling,
dispatch and trading, tariff payable for specified duration will be calculated
by this module. Tariff calculation results will be made available as reports in
the format desired by the user.
Network
Management module:
Network
Analysis Module: deals with voltage stability analysis, transmission &
distribution losses calculation as well as optimal power flow computation. EOP
supports online integration with a transmission/distribution SCADA using OPC,
DDE or similar interfaces. This allows for events from the field to be simulated
in the NAM sub-module and analysis to be performed in an online fashion.
DER
/ DSM: This module deals with integrating distributed energy resources
(DER)
and demand side management (DSM) solutions in a network to derive maximum
benefits in a market mechanism. Technical and commercial implications of turning
on a specific DER or DSM resource are analyzed so that online decision making by
the concerned operator (or an automation system!) is possible.
Fault
Analysis: This is a standard SoE (Sequence of Events) and fault analysis
module. Data from multiple IEDs can be collected and correlated in a single
sources using the integration mechanisms provided by EOP. Root cause analysis as
well as fault distance analysis for a network fault can be evaluated through
this sub-module.
SCED:
deals with security constrained economic dispatch. Similar to the MOR solution
in Plant Management Module, SCED deals with multiple generation sources in a
transmission network (while the MOR deals with multiple generating units in a
single station). Transmission constraints and losses are taken into account to
evaluate the optimal power dispatch strategy.
Modeling
and Simulation:
Boiler
simulation: Thermodynamic model for a fossil fired generating unit is
developed here. This is not a standard solution, as the applicable model will
vary from plant to plant and unit to unit. This model enables evaluation of
different operation strategy. This model also provides the input for the
state-variable control algorithm.
Forecasting
module: deals with forecasting load and frequency in short to medium term by
developing neural network models for the same. Such models can provide
invaluable assistance in scheduling and maintenance planning.
What-if
analyses: This sub-module allows operator to simulate the inputs to
different modules in EOP and view the results. This will operator to check out
the effectiveness of various operation strategy. For example, it can help
operator to decide whether heat rate can be improved by changing certain process
parameter values or to inspect the benefits of a specific unit loading scheme.
Analytics:
Report Engine: Reports from different modules in EOP as well as reports
integrating information spanning multiple modules are served by this module. All
reports are delivered through a browser interface, requiring no client software
installation. Reports can be exported to any desired format such as .pdf
(Acrobat), .xls (MS Excel), .rtf (MS Word) etc. A report builder is also
provided so that user can create their own reports
Configuration:
Configuration
module: All configuration data for EOP is stored in XML format. This allows
for ease of maintenance and portability. Configuration options can be changed
through a browser interface by any authorized user. A separate configuration
loader is provided to ensure that administrator approval is obtained before
loading any configuration changes to the application.
