POSSIBILITIES AND PERSPECTIVES OF THE CONSUMERS-REGULATORS APPLICATION IN SYSTEMS OF FREQUENCY AND POWER AUTOMATIC REGULATION

Abstract

The Integrated Energy System (IES) of Ukraine functions as part of the European Union (EU) electric power system ENTSO-E. Each country whose IES operates in the ENTSO-E structure must ensure the presence of a full-fledged fre-quency and power automatic control system (AFPCS, AFPC system) in the national IES. The only exception is the IES of Ukraine, because its inclusion in the ENTSO-E happened during martial law and in the absence herewith of a full-fledged AFPC system. It violates the cornerstone requirements of the ENTSO-E structure formation. In the post-war period, the IES of Ukraine will be obliged to complete its own, full-fledged AFPCS as soon as possible. Three structures of the AFPC system development of the Ukrainian IES were studied: according to the traditional principle (on the basis of generators-regulators); on the basis of heat consumers-regulators with the involvement of heat pump installa-tions and on the basis of heat consumers-regulators using electric heat generators that provide energy for the central-ized heat supply system. Calculations and analysis of technical and economic indicators showed that the traditional structure of AFPCS extremely loses to both structures built on consumers-regulators. Significantly better of these two systems is the AFPCS, built on consumers-regulators in the form of electric heat generators. It provides an annual net profit of more than 1.8 billion USD, with a payback period of about 0.5 years, reduces by 2.7 billion m3 of natural gas consumption, reduces by 13.9 billion USD needs capital investment, has short construction deadlines.
