Integration, Billing and Optimization Solutions helps Integrated Utilities
or Power Generation Companies to have Local and Enterprise View of their
Power Generation, Power T&D and Energy Trading data in real-time online
and make real-time decisions and analysis and enable their various systems
to interact and exchange information and carry out business functions like
billing and energy audit.
Energy is an ï¿½onlineï¿½ 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
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
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.
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.
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
Energy Market 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.
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.
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.
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
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
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:
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.
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.
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
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
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.
