Abstract—

The prices for electricity from renewable energy sources (RES) tend to decrease around the world and have already become lower than 1.5 rubles/(kW h) in the most advantageous projects. However, this indicator in Russia has essentially higher values both at present and in the forecast for 2035, which is caused by the system effect of RES integration in the power system. In fact, renewable energy and conventional energy are antipodes in Russia and are in contradiction with respect to each other. The article substantiates the possibility of harmonizing them with each other from the viewpoint of the universal organizational science called tectology and gives examples of technological solutions for implementing this: changing the operation modes of electrical loads in the compositions of consumer electrical systems and development of distributed cogeneration in accordance with the schedule of electrical rather than heat loads as a result of separating the heat-recovery and consumption processes in time by using thermal energy-storage devices. In fact, this refers to achieving better structural stability of the energy sector based on an alternative concept of its development and transition to optimizing the operation of the inseparable process chain “production–consumption of fuel and energy resources,” which also includes new, renewable sources. Apart from decreasing the costs for integrating RES into the power system and making the prices for electricity from RES in Russia commensurable with those around the world, this will also result in a more efficient power supply as a consequence of more uniform loading of thermal and nuclear power plants, the use of the nonutilized potential of decreasing the specific fuel consumption for electricity production in the cogeneration mode, and decreased losses in distribution networks.

降低可再生能源整合的成本:一种使可再生能源更容易获得的方法

摘要-

世界范围内可再生能源 (RES) 的电力价格趋于下降,并且在最有利的项目中已经低于 1.5 卢布/(kW h)。然而,该指标在俄罗斯目前和2035年的预测中都有较高的值,这是由可再生能源并入电力系统的系统效应引起的。事实上,可再生能源和常规能源在俄罗斯是对立的,相互矛盾。这篇文章从称为 tectology 的普遍组织科学的角度证实了将它们相互协调的可能性,并给出了实现这一点的技术解决方案的例子:通过利用热能储存及时分离热回收和消耗过程,改变消费电力系统组成中的电力负荷运行模式,并根据电力而不是热负荷的时间表发展分布式热电联产设备。实际上,这是指基于能源部门的发展和过渡到优化不可分割的“燃料和能源资源的生产-消费”过程链的运行的替代概念,实现能源部门更好的结构稳定性,其中还包括新的、可再生的来源。除了降低将可再生能源并入电力系统的成本,并使俄罗斯可再生能源的电力价格与世界各地的价格相适应外,
