Integrated energy system is a useful tool for achieving the"dual-carbon"goal. In order to explore the demand-side adjustable potential of the comprehensive energy system for lowering carbon emissions, this paper proposes an optimal operation model that accounts for demand response under a carbon trading mechanism. Initially, the demand response is classified into two categories based on the characteristics of the load response. Additionally, a carbon trading mechanism is built for the integrated energy system by allocating the carbon emission quotas for the system using the baseline technique, which is free of charge. The actual carbon emissions from the gas turbine and gas boiler are also taken into account. Ultimately, a low-carbon optimization operation model of the integrated energy system is established, with the goal of minimizing the total cost of energy purchase, carbon trading, and operation and maintenance. The suggested model's validity is then confirmed through four types of typical scenarios.

A CBjT high-speed operational amplifier (op-amp) has been developed and studied, which differs from known in its modified input stage (IS), as well as the architecture of the intermediate “folded” cascode (FC). The proposed circuits IS and FC circuits solve the problem of increasing the maximum slew rate of the output voltage (SR) in large-signal mode by more than 10 times. In the LTspice environment, computer simulation of an op-amp on complementary bipolar transistors was performed, which shows that the use of the developed transient correction circuits makes it possible to increase SR from 103 V/μs to 1408 V/μs. The logarithmic amplitude-frequency characteristics of the op-amp under study are given for different options for its inclusion - with and without general negative feedback. The leading and trailing edges of the op-amp transient process were studied with an input rectangular pulse signal with an amplitude of 5V at different values of the capacitance of the additional correction capacitor $C_{\mathbf{k1}}$. The simulation results are presented in the form of a table that establishes the relationship between the numerical values of the maximum rate of rise of the output voltage of the op-amp and the capacitance $C_{\mathbf{k1}}$. The considered op-amp is recommended for use in various automation devices and communication systems, for example, discrete-analog filters on switched capacitors, high-speed ADC drivers, etc.
