Abstract
With the large-scale grid connection of new energy sources, their high randomness and volatility bring great challenges to the grid. Using deep learning to predict uncertain renewable energy resources has emerged as a promising technology. This paper presents a deep learning-based approach to forecast the power generation of wind and photovoltaic power with the aim of reducing the adverse effects of uncertainty in optimal scheduling problems. Meanwhile, the multi-objective optimization model of the regionally integrated energy system is established by combining the system operation and maintenance cost and system revenue. The system is optimized online by an accelerated particle swarm optimization. The results show that compared to the online optimization with the single APSO method, the operation and maintenance costs are reduced by 60.8 CNY on a typical cooling day and 52.01 CNY on a typical heating day. The utilization rate of renewable energy in the cooling and heating periods is improved by 5.88 % and 0.65 % and the CO2 emission reduction rate is 6.99% in the system. The integrated energy system online optimization method proposed in this study based on deep learning and accelerated particle swarm optimization can reduce operation and maintenance costs, improve the utilization rate of renewable energy.

Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview.
• Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation.
• Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design.
• Substation work: equipment design, protection and control systems.
• Distribution techniques, equipment development, and smart grids.
• The utilization area from energy efficiency to distributed load levelling techniques.
• Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
