The Introduction of Base Power Supply Used Surplus Electric Power from Photovoltaic System
Authors: , , ,
Abstract: The interconnection of large quantities of the distributed power source, such as PV power source, to the power electric system is anticipated, and as a result, the fluctuations of voltage and frequency will increase and make the adjustment of the demand and power supply balance difficult. The present paper describes new method of the large-scale PV System used Pumped Storage System (PSS) to store the electric power from large-scale PV system in the daytime and power supply in the nighttime as base power supply. Large-scale PV system with PSS is studied by computer simulation. The contents include the installed position of PSS, the capacity of PSS, capacity of transmission line, power generation cost, and base power supply. It will be possible to use base power supply from large-scale photovoltaic power instead of electric power from nuclear or thermal power station, satisfy demand and reduce or stop the output of nuclear station or thermal power station, use the surplus electric power, maintain a stable power supply, energy-saving, and a suitable adjustment of the power demanded-supply balance.
