A smart grid puts information and communication technology into electricity generation, delivery, and consumption, making systems cleaner, safer, and more reliable and efficient. Ministry Of Power Definition: A smart grid integrates advanced sensing technologies, control methods, and integrated communications into the current electricity grid. 9/13/2011 2 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTWhat does the concept of Smart Grid look like?: What does the concept of Smart Grid look like? 9/13/2011 MUKUL SHARMA, EEE DEPARTMENT, CTIEMT 3 Electrical Infrastructure “Intelligence” InfrastructureSmart Grid Applications: Smart Grid Applications Distributed Generation and Alternate Energy Sources Self-Healing Wide-Area Protection and Islanding Asset Management and On-Line Equipment Monitoring Demand Response and Dynamic Pricing Participation in Energy Markets Shared Information – Continuously Optimizing – Intelligent Responses! Real-time Simulation and Contingency Analysis 4 9/13/2011 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTSmart Grid Benefits: Smart Grid Benefits Economic Development New Jobs: The manufacture, installation, operation and maintenance of the smart grid and its components will create new jobs within the state. Innovation: Smart grid innovation will enable the growth of business while rewarding customers with valuable new products. Lower Costs: Costs rise over time and energy is no exception, but the smart grid should provide less costly energy than otherwise would be possible. As such, it will save customers money which can be invested or consumed as they choose. 5 9/13/2011 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTSmart Grid Benefits-cont: Smart Grid Benefits-cont Customer Satisfaction Higher Customer Satisfaction: The combination of lower costs, improved reliability and better customer control will raise satisfaction among all types of customers (residential, commercial, industrial, institutional). Improved Reliability: Smart grid will reduce and shorten outages and improve the quality of power. Shorter Outages: The incorporation of advanced sensors and measurement (PMU), communication networks and smart systems will allow an unprecedented degree of system visibility and situational awareness of the electric power system. Smart grid will result in shorter outages through its “islanding” and “self-healing” features. Customer Energy/Cost Savings: As pricing becomes more transparent and is aligned with the underlying economics of generation and distribution, customers’ decisions to save money will benefit society as well Highest Security: Security will be incorporated into the design of the smart grid and will require the implementation of practices and procedures by individual stakeholders. In this way, the physical and cyber security risks can be managed to the highest standards possible. Timely renewables : Smart grid is the enabler of more renewable energy. Its development will allow for the timely incorporation of these sustainable sources of power in a user-friendly, cost-effective manner. 6 9/13/2011 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: 9/13/2011 7 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPillars of Smart Grid: Pillars of Smart Grid 9/13/2011 8 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTSMART GRID IN TRANMISSION : SMART GRID IN TRANMISSION 9 9/13/2011 9 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: 10 Technology Integration & Grid Management Need for development of Smart Grid having features like- 9/13/2011 10 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: CONCEPTUAL MODEL FRAMEWORK OF SMARTGRID 9/13/2011 11 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: 9/13/2011 12 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: ROLE OF PHASOR MEASUREMENT UNIT (PMU) IN WIDE AREA MONITORINGAND CONTROL A device (mostly microprocessor based) which reports the magnitude and phase angle of an analog and /or derived phasor with respect to the global time reference, as per the synchrophasor standards ( IEEE 1344, IEEE C37.118). 9/13/2011 13 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: 9/13/2011 14 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: 9/13/2011 15 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: Time synchronized sub-second data Dynamic behavior observing Directly provides the phase angles (State Estimation to State Measurement) Improve post disturbance assessment High data rates and low latency due to computation 16 Benefits of PMU 9/13/2011 16 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: 9/13/2011 17 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: APPLICATION OF FACTS 9/13/2011 18 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: APPLICATION OF FACTS continued. .. 9/13/2011 19 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: In a power grid a certain amount of power eneration needs to be in service for back-up, emergency, use. This is typically referred to as spinning reserve. The amount differs from area to area, but in general an interconnected power system needs the same amount available as the largest unit in order to cope with a loss of the largest generation unit. The traditional solution is to run generators below maximum power in order to provide this capability.If dynamic (almost instantaneous) electrical power is available from sources such as the SVC Light Energy Storage the amount of generation on-line can be reduced. The system will support the grid continuously with reactive power and in case of loss of generation the system will push active power into the grid until new generation is online , typically within 20 minutes SPINNING RESERVE 9/13/2011 20 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: Generators giving local reactive power support are being retired, this disturbs reactive power balance. Load sensitivity regarding both fundamental frequency and harmonic voltages is increased. Customers are more sensitive to outages. Changed and often reversed power flow calls for studies and actions. An SVC at the Connection Point can be used to control the entire, or part of, the reactive power. An SVC at the Connection Point makes it possible to minimize the losses within the wind farm and mitigates the risk for over voltages REACTIVE POWER BALANCE POSSIBLE FACTS APPLICATION 9/13/2011 21 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTPowerPoint Presentation: SMART GRID IN DISTRIBUTION 9/13/2011 22 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTSMART GRID IN DISTRIBUTION: SMART GRID IN DISTRIBUTION Distribution Automization Demand Optimaization - Selective Load Control Operation –Islanding of Micro-grids 9/13/2011 23 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTDISTRIBUTION AUTOMIZATION/OPTIMIZATION: DISTRIBUTION AUTOMIZATION/OPTIMIZATION Managing Distribution Network Model Outage management and AMI Integration DMS & Advanced Switching Applications Integrated Voltage / VAR Control 9/13/2011 24 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTDemand Optimization: Demand Optimization Demand Response – Utility Demand Response – Consumer Demand Response Management System In Home Technology enabling 9/13/2011 25 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTDEMAND OPTIMIZATION: DEMAND OPTIMIZATION Smart Metering – Automatic, Time of Use, Consumer Communication & Load Control Communications : Automated Metering Infrastructure (AMI) – LAN, WAN, HAN DRMS (Demand Response Management) In Home enabling technology Demand in three category: Immediate, Deferrable, Storable Customer aggregation & De-aggregation required for Peak shifting 9/13/2011 26 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTDemand Optimization: Advanced Web Portal: Demand Optimization: Advanced Web Portal 9/13/2011 27 MUKUL SHARMA, EEE DEPARTMENT, CTIEMTControl Center with Service Oriented Architecture (BUS): Control Center with Service Oriented Architecture (BUS) Having GIS (geo-spatial Information Systems), AMI, SAP (ERP), OMS (Outage management System), DMS (Distribution Management System), EMS (Energy Management System), DRMS (Demand Response management System).
