  1. 1. GRID VOLTAGE REGULATION SUBMITTED BY:- ADITYA NEHWAL ROLL NO - 02 S7 - EEE
  2. 2. CONTENTS  INTRODUTION  OBJECTIVE  VOLTAGE REGULATION DESCRIPTION  BLOCK DIAGRAM DESCRIPTION  SIMULATION RESULT ANALYSIS  SMART GRID CONCEPT  ADVANTAGES & DISADVANTAGES  APPLICATION  CONCLUSION
  3. 3. INTRODUCTION  Grid Voltage Regulation utilizing storage batteries in PV solar–wind plant based distributed generation system.  Utilities have voltage regulation equipment at various points of the distribution system to insure customers receive the proper voltage at their meter during any load level.  The past and even present voltage regulation philosophy was not developed with widespread, so Distributed Energy Resources comes in mind at customer premises.
  4. 4. OBJECTIVE  Power supply and demand balance with high penetration of renewable energy.  Distribution voltage stability in case of a large amount of distributed generators.  Power-saving and energy conservation.  Blackout prevention and outage time reduction.  Demand response in severe power system condition.
  5. 5. VOLTAGE REGULATION DESCRIPTION  Voltage regulation: The degree of deviation of terminal voltage ,when load current is applied at any power factor or the percentage change in the output voltage from no-load to full-load.  Regulation = ( [V]nl-[V]l) [V]nl Where [V]nl & [V]l are the no-load and load terminal voltages.
  6. 6. ELECTRICAL GRID:  An electrical grid is an interconnected network for delivering electricity to suppliers to consumers.  It consist of generating station that produce electrical power, high voltage transmission lines that carry power from distant sources to demand centre & distribution lines that connect individual customers.  The AC electrical grids are composed of substations connected to each other by overhead, underground, lines.
  7. 7. BLOCK DIAGRAM DISCRIPTION Proposed utilisation solar-wind farm
  8. 8. Operational modes: The voltage and flow of power at PCC(point of common coupling) is monitored. During night-time If the PCC voltage is observed to increase beyond a certain level. significant amount of reverse power flow is detected, the battery charging loop is activated. Part of the wind generated real power (ΔPWF) is extracted and utilized to charge the batteries such that the voltage at PCC will be regulated. .
  9. 9. Several batteries can be charged simultaneously if very high amount of reverse power flow causing significant voltage rise at PCC is noticed. PVSolar – wind farm work together for charging and discharging of battery. During the day-time, this stored energy in the batteries is delivered back to the PCC
  10. 10.  In morning hours or late afternoon hours when the power generated from PV solar farm is not at its peak, the battery will be connected in parallel with solar farm generated output.  PV solar farm and storage battery will simultaneously support the load power demand.  If the power generated by a DG is more than load demand connected downstream of the PCC, the excess power flows back towards the main grid.
  11. 11. SIMULATION RESULT ANALYSIS
  12. 12. SYSTEM FEEDER VOLTAGE CONTROL USING PV SOLAR FARM INVERTER AND STORAGE BATTERY (DURING BATTERY CHARGING).
  13. 13. INVERTER CURRENT AND GRID CURRENT PROFILES DURING BATTERY CHARGING.
  14. 14. SYSTEM FEEDER VOLTAGE CONTROL OF INVERTER AND STORAGE BATTERY (DURING BATTERY DISCHARGING) .
  15. 15. INVERTER AND GRID CURRENT PROFILES DURING BATTERY DISCHARGING.
  16. 16. SMART GRID CONCEPT  A smart grid is a modernized electrical grid that uses analogue or digital information and communications technology  It act on information about the behaviours of suppliers and consumers.  It work in automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.
  17. 17. SMART GRID NETWORK
  18. 18. ADVANTAGES  Balance Management Validation Operation  Distribution Management Validation Operation  Total Operation (Balancing and Distribution Management)  During each of these operations mode power shortage can maintain.  Troubles such as lighting, voltage drop, short circuit and so on will be tested. .
  19. 19.  Distributed Generation increases the reliability of power supply to the consumers.  Significantly reduces Transmission and Distribution losses.  It improve the voltage profiles, power quality and supports the voltage stability of the system.  This allows the system to withstand higher loading conditions and  Reduce the cost of Infrastructure for building the transmission and distribution systems.  Utilization of solar-wind can be made part of the smart grid or micro grid to improve the efficiency of the system.
  20. 20. DISVANTAGES  Wind turbines will have visual, acoustic and bird life impact.  This farms require large area compared to the conventional technologies for the same installed capacity.  The output of some of the renewable energy sources such as wind, PV are variable and difficult to predict.  Connecting the Distributed Generation sources to the grid is complex.  Protection design requires good communication between Distributed Generation project developer and Grid authorities. during the design.
  21. 21. APPLICATION  Voltage sags that degrade power can stem from a number of sources at the utility.  Useful in voltage trips, recloses, fault depressions, commutations, and inductive electrical loads.  Industrial loads that involve electric arc furnaces, large motor starts and stalls, thus disrupting of voltage can reduce.  It is very useful to PQ-IVR(power quality of industrial voltage restorer) system.
  22. 22. CONCLUSION  The bidirectional inverter of PV solar farm is utilized as a battery charger especially during the night-time to charge the batteries  voltage rise (due to a substantial amount of reverse power flow from the wind farm) is controlled by utilizing the solar farm inverter to charge the batteries.  The solar farm inverter is operated as a three-phase controlled rectifier which draws sinusoidal currents at unity power factor operation  A new generation of devices for voltage regulation based on solid-state technology are in the early commercialization stages.
  23. 23.  Distribution regulation involves a "regulation point": the point at which the equipment tries to maintain constant voltage.  Customers closer than this point experience the opposite effect: higher voltage at high load, and lower voltage at light load.
