Abstract

Micro coal-fired units (MCFU) and combined heat and power plants (CHP) in integrated energy system (IES) will emit a large amount of carbon dioxide when providing loads to customers, which will lead to higher operating costs of IES. To solve this challenge, an optimal dispatch model of power-to-gas (P2G) and methane reactor (MR) considering the reward and punishment costs based on carbon emission trading mechanism is proposed, to reduce carbon emissions of IES and enhance the accommodation of renewable energy (RE). Subsequently, considering the uncertainty of RE, a combination optimization method for MCFU and CHP units is developed based on the Lagrange multiplier method. Finally, considering the mechanism of electricity spot market (ESM), a transaction strategy for IES participating in ESM is proposed to further enhance the accommodation of RE. The effectiveness of the proposed framework is demonstrated through simulations.

基于电力现货市场碳排放的综合能源系统最优调度框架

综合能源系统(IES)中的微型燃煤机组(MCFU)和热电联产电厂(CHP)在向客户提供负荷时将排放大量的二氧化碳，这将导致综合能源系统(IES)的运行成本较高。针对这一挑战，提出了一种考虑奖惩成本的基于碳排放交易机制的P2G和甲烷反应器(MR)最优调度模型，以减少IES的碳排放，增强可再生能源(RE)的适应性。随后，考虑RE的不确定性，提出了基于拉格朗日乘子法的MCFU和CHP机组组合优化方法。最后，考虑到电力现货市场(ESM)的机制，提出了IES参与ESM的交易策略，以进一步增强可再生能源的适应性。通过仿真验证了所提框架的有效性。

期刊介绍： Journal of Circuits, Systems, and Computers covers a wide scope, ranging from mathematical foundations to practical engineering design in the general areas of circuits, systems, and computers with focus on their circuit aspects. Although primary emphasis will be on research papers, survey, expository and tutorial papers are also welcome. The journal consists of two sections: Papers - Contributions in this section may be of a research or tutorial nature. Research papers must be original and must not duplicate descriptions or derivations available elsewhere. The author should limit paper length whenever this can be done without impairing quality. Letters - This section provides a vehicle for speedy publication of new results and information of current interest in circuits, systems, and computers. Focus will be directed to practical design- and applications-oriented contributions, but publication in this section will not be restricted to this material. These letters are to concentrate on reporting the results obtained, their significance and the conclusions, while including only the minimum of supporting details required to understand the contribution. Publication of a manuscript in this manner does not preclude a later publication with a fully developed version.
