The determination of maximum capacities of solar power plants in IPS of Ukraine
Journal Title: Проблеми загальної енергетики - Year 2016, Vol 0, Issue 2
Abstract
The maximum value of the solar power plant (SPP) in the power system depends on the performance reserve and regulating capacity of the automatic frequency and power control (AFPC) system. It is believed that the regulatory capacity of the system AFPC enough if AFPC is able to compensate for perturbations caused by the action of SPP. The frequency deviation in the power system should remain in the range of ±0.02 Hz (according to the requirements of ENTSO-E) or ±0.2 Hz (actual requirements for IPS of Ukraine). Given the approach (program of experiments, the algorithm of their conduct) to the determination of maximum capacities of SPP as a part of IPS of Ukraine. As a result of experiments obtained values of maximum capacity of SPP that the system AFPC is able to compensate under different initial conditions. Among them: the different types and composition of regulators (hydrounits of hydroelectric power plant, coal-fired thermal power plants, controllable loads); the permissible frequency deviation of 0.2 Hz or 0.02 Hz; the maximum power the various regulators, and SPP. As a result of research, including it is established that, for example, for a permissible frequency deviation of 0.2 Hz in IPS of Ukraine with AFPC based on the pulverized coal (PC) power station with a reserve of 1000 MW power limit SPP is 581 MW, whereas for compensation of SPP power of 1 GW need generators-regulators PC thermal power plant with the capacity of 9.3 GW. This variation is explained by the self-regulatory effect which is manifested at AFPC with PC thermal power plants due to low performance of this type of regulators. To compensate for a 1 GW SPP ceteris paribus will require 310 MW generators-regulators hydroelectric power plant of 300 MW or controllable load.
