Direct current provides accumulation of electricity and is therefore necessary when using renewable energy sources. Hydrogen energy storage devices in the form of fuel cells are the most effective and environmentally friendly way of energy storage and conservation. Shortcomings of electric power networks compared with DC networks in terms of stability, controllability, reliability and redundancy are noted. The necessity of transition from digitalization in the form of automated process control systems to smart grids, and subsequently to multi-agent DC networks with a high degree of redundancy, is revealed. Besides, the paper deals with application of distributed generation consisting of traditional and renewable energy sources, as well as accumulators and static converters. Characteristics of the above mentioned elements are given for simulating the modes in order to select the structure and control algorithms that provide increased power supply reliability.

直流电可提供电能积累，因此在使用可再生能源时必不可少。燃料电池形式的氢能存储设备是最有效，最环保的能量存储和节约方式。注意到电力网络与直流网络相比在稳定性，可控制性，可靠性和冗余性方面的缺点。揭示了从自动化过程控制系统形式的数字化过渡到智能电网，以及随后向具有高度冗余度的多代理DC网络过渡的必要性。此外，本文还讨论了由传统能源和可再生能源以及蓄能器和静态转换器组成的分布式发电的应用。
