System Research in Energy| Zusammenfassung: | It is shown that the main parameter determining the required maximal value of the maneuverable power of a power system is the depth of night depression of its schedule of electrical loads. We determined the deficiency of maneuverable power of the United Energy System of Ukraine as of 2018. The needs for accumulation of thermal energy in district heating systems are determined at mounting electric heat generators in them for the control of load of the UES of Ukraine. For 100% coverage of the deficiency, these requirements are 26,030 Gcal or, for 90%, 22,953 Gcal per day.We analyze the processes of accumulation of thermal energy in the main heat networks of district heating systems for the heating and non-heating periods as applied to the design and actual temperature charts. We estimate the limiting daily heating accumulation possibilities of thermal networks, which make up for the design temperature schedule 56,719 Gcal, for real 35,112 Gcal, and in the non-heating period 15,929 Gcal.It is noted that, in practice, the complexes of electric boilers and heat pumps will be used as electric heat generators. A part of thermal energy, which will be produced by them, will replace the thermal energy of district heating boilers, and the rest will be accumulated in heating networks. With a reasonable choice of the composition of electric heat generators and the amount of replacement of thermal energy of standard boilers, the existing main heating networks can provide efficient functioning of electric heat generators when used as consumers-regulators in covering electrical load schedules in the UES of Ukraine. |
