摘要

随着分布式光伏的快速发展,许多分布式光伏设备被接入电网,这就需要对含有高比例分布式光伏的电网进行优化调度。本文建立了一种新的结合高比例光伏发电的电力系统日前优化调度模型。模型中考虑了分时电价对用户的影响以及储能电站对电力的调节。本文的主要贡献在于为分布式光伏比例较高的电网提供了更好的解决方案,减少了碳排放并改善了光伏消耗。最优调度采用了一种解决方案,即野马优化器(WHO)。结果表明,与粒子群算法相比,野马优化器节省了 16% 的成本,减少了 28% 的火电碳排放,提高了 24% 的分布式光伏利用率。野马优化器是一种更好的优化方法,当应用于分布式光伏比例较高的电网优化调度时,可以降低分布式光伏弃光率,减少成本。

The source-load-storage coordination and optimal dispatch from the high proportion of distributed photovoltaic connected to power grids
With the rapid development of distributed PV, many distributed PV devices are connected to the power grid, which is essential to optimize the scheduling in the power grid containing a high proportion of distributed PV. In this paper, a new day-ahead optimal dispatching model of a power system combined with the high proportion of photovoltaic is established. The impact of time-of-use tariffs on customers and the regulation of electricity by energy storage plants are considered in the model. The main contribution of this paper is that providing a better solution for grids with a high proportion of distributed photovoltaic, reducing carbon emissions and improving photovoltaic consumption. A solution approach i.e., Wild horse optimizer (WHO) is employed to optimal dispatch. The results show that compared with the Particle swarm algorithm, using the Wild horse optimizer has saved 16% costs, reduced 28% in thermal power carbon emissions, and increased 24% in distributed PV utilization rates. Wild horse optimizer is a better optimal approach which can reduce distributed PV abandonment rates and decrease costs when applied to the optimal scheduling in the grid with high percentage of distributed photovoltaic.

期刊介绍: Journal of Engineering Research (JER) is a international, peer reviewed journal which publishes full length original research papers, reviews, case studies related to all areas of Engineering such as: Civil, Mechanical, Industrial, Electrical, Computer, Chemical, Petroleum, Aerospace, Architectural, Biomedical, Coastal, Environmental, Marine & Ocean, Metallurgical & Materials, software, Surveying, Systems and Manufacturing Engineering. In particular, JER focuses on innovative approaches and methods that contribute to solving the environmental and manufacturing problems, which exist primarily in the Arabian Gulf region and the Middle East countries. Kuwait University used to publish the Journal "Kuwait Journal of Science and Engineering" (ISSN: 1024-8684), which included Science and Engineering articles since 1974. In 2011 the decision was taken to split KJSE into two independent Journals - "Journal of Engineering Research "(JER) and "Kuwait Journal of Science" (KJS).
