Distributed Volt Ampere Reactive Power Compensation of Modern Power System to Control High Voltage
https://orcid.org/http://orcid.org/0000-0002-2400-9726
Rajasthan power system has comprehensively extended its role in adding renewables. But at present, this existing network is lacking of capacitive var compensation at high voltage grid substation. Due to renewable integration and variable load behavior, the state load dispatch centers (SLDC) are not able to handle the situation of overvoltage as recorded by database collected over the financial year 2018–2019. SLDC instructs 400 kV grid substation to control high voltage via opening of lightly loaded lines and switching of capacitors, etc. The haphazard arrangement where some substations are over compensated while rest are undercompensated results in violating of planned voltage levels mandated by Indian Electricity Grid Code 2006 and CEA’s planning criteria 2013. Concerning toward the reduced level of compensation accessible at present, no methodology is followed by operators to cope high voltages. This paper introduces a planning level methodology to provide 100% line compensation as per certainty by installing of reactors in the grid. A comparative case study between proposed and existing test network to improvise voltage profile of power system is carried out. Dynamic case studies are also carried out to check the feasibility of technique proposed by varying dynamic load of 12,874–10,370 MW. The impact of planned and installed reactors on desired locations is tested in terms of impact on voltage profile of buses, transformer/generator var altitude analysis, etc. at last.
