Connections among multi-energy systems become increasingly closer with the extensive application of various energy equipment such as gas-fired power plants and electricity-driven gas compressor. Therefore, the integrated energy system has attracted much attention. This paper establishes a gas-electricity joint operation model, proposes a system evaluation index based on the energy quality character after considering the grade difference of the energy loss of the subsystem, and finds an optimal scheduling method for integrated energy systems. Besides, according to the typical load characteristics of commercial and residential users, the optimal scheduling analysis is applied to the integrated energy system composed of an IEEE 39 nodes power system and a 10 nodes natural gas system. The results prove the feasibility and effectiveness of the proposed method.

The complementary micro-energy network system consisting of solar photovoltaic power generation (solar PVs) and micro-gas turbine (MGT), which not only improves the absorption rate and reliability of photovoltaic power, but also has the advantages of low emission, high efficiency, and good fuel adaptability, has become one of the most promising distributed power systems in the field of micro grid. According to the development of current technology and the demand of actual work, this research described the domestic and foreign development of micro-energy network system based on solar PVs and MGT. Moreover, it analyzed the challenges and future development regarding the micro-energy network system in planning and design, energy utilization optimization and dispatching management, and system maintenance, respectively. Furthermore, it predicted the future development of the key technology of the multi-energy complementary system. These results will be beneficial for the progress of this field both in theory and practice.

The relation between power-to-gas technology (P2G) and energy interconnection becomes increasingly close. Meanwhile, the participation of flexible load on user side in system optimization has attracted much attention as an efficient approach to relieve the contradiction between energy supply and energy demand. Based on the concept of energy hub, according to its series characteristic, this paper established a generic multi-energy system model using the P2G technology. The characteristic of flexible load on user side was considered and optimal dispatch analysis was made, so as to reduce the cost, to reasonably dispatch the flexible load, to reduce the discharge, to enhance the new energy output, and to increase the power-to-gas conversion efficiency. Finally, a concrete analysis was made on the optimal dispatch result of the multi-energy system using the P2G technology considering flexible load on user side in the calculating example, and optimal dispatch of the system was verified via four different scenarios. The results indicate that cooperative dispatch of multi-energy system using the P2G technology considering flexible load on user side is the most economic, and can make a contribution to absorption of new energy and P2G conversion. In this way, environmental effects and safe and stable operation of the system can be guaranteed.

能源革命是实现能源系统与经济社会、生态环境协调发展的重要途径,能源战略对国家和地区能源革命进程的推进具有重大影响。本文提出了一种用于能源战略分析的“SEGO”系统分析方法,从能源挑战、能源系统、能源治理和能源市场4个要素及其关系出发,对全球能源转型及我国能源革命战略进行了系统分析。研究表明,全球面临能源公平、能源安全和能源绿色化多重能源挑战,且缺乏强有力的全球能源治理,导致全球能源系统转型总体较为缓慢,中国被期望在推动全球能源系统转型中起到更加积极主动的作用;我国的能源可持续发展逐步推进,在能源革命过程中面临能源系统集成等挑战,但政治意愿坚定,有效推动了能源转型,实现了少耗能、少排放。研究建议,我国能源革命应从经济社会、生态环境的全景视角下,做好能源发展的全局系统优化和全程精细管控,尤其做好不同类型能源网络之间共建、共享、共调的深度协同,加速能源新技术、新产业的颠覆式创新。
