摘要

的目的。考虑估算通过领土电网组织(tgo)的电网传输电力的服务成本的问题,包括具有tgo地位的大型工业企业及其自己的发电。考虑到电力来源的技术和经济特点,制订一种方法来计算这类企业电力供应系统各组成部分的电力损失费用。制定一种方法,以确定个别来源和消费者对电力损失及其成本的份额贡献。计算某工业TGO企业的电力损耗成本及电源对电力损耗的贡献结构,并得出结论。方法。在求解任务集时,采用了计算供电系统稳态模式的方法。结果。本文阐述了课题的相关性,建立了计算方法,在大型工业电力中心条件下,考虑了工业企业的输电服务用户付费系统及其与流量分布的关系。分析了供电系统中各电源对电力损耗的贡献结构。已制定办法,在考虑电源在供电系统中的位置的情况下,调整购损电价。提出了降低第三方消费者对电力传输服务成本补偿不足程度的建议。建议为此目的使用由损失成本决定的技术电力损失标准(NTLE)。结论。在目前的监管框架下,TGO企业在计划中分配子用户的方式是,考虑到损失目标而确定的实际NTLE不超过计算的NTLE。在这种情况下,没有将损失成本从子用户转移到TGO企业自己的消费。同时,次级用户不会产生额外的成本,因为他们以锅炉电价向担保供应商付款。用于这些目的的非强制转让费用必须根据损失费用确定,同时考虑到来源的特点。TGO企业的网络损失赔付份额减少了,这部分损失由TGO企业自己消费,而不是由次级用户补偿。从而降低了TGO企业的电力成本及其在成品成本中的份额。

Identification of the sharing contribution of the power supply system power sources to the electricity losses and their cost
THE PURPOSE. Consider the problems of estimating the cost of services for the transmission of electricity through the electric networks of territorial grid organizations (TGOs), including large industrial enterprises with the status of TGOs and their own generation. Develop a methodology for calculating the cost of electricity losses in the elements of the power supply system of such enterprises, taking into account the technical and economic characteristics of the sources. Develop a methodology for determining the share contribution of individual sources and consumers to electricity losses and their cost. Calculate the cost of electricity losses and the structure of the contribution to it of power sources of an industrial TGO enterprise and draw conclusions. METHODS. When solving the tasks set, methods for calculating steady-state modes of power supply systems were used. RESULTS. The article describes the relevance of the topic, created calculation methods, in the conditions of a large industrial power center, the system of payment by sub-subscribers of an industrial enterprise for services for the transmission of electricity and its relationship with the flow distribution is considered. The structure of the contribution of power sources to the losses of electricity in the power supply system is analyzed. An approach has been formulated to adjust the individual tariff for the purchase of electricity losses, taking into account the placement of power sources in the power supply system. Recommendations are given to reduce the degree of undercompensation of the cost of electricity transmission services by third-party consumers. It is proposed to use for these purposes the norms of technological losses of electricity (NTLE), determined by the cost of losses. CONCLUSION. Under the current regulatory framework, it is in the interests of TGO enterprises to distribute sub-subscribers in the scheme in such a way that their actual NTLE, determined taking into account the targeting of losses, does not exceed the calculated NTLE. In this case, there is no transfer of the cost of losses from sub-subscribers to the own consumption of the TGO enterprise. At the same time, sub-subscribers do not incur additional costs, since they pay off with the guaranteeing supplier at the boiler tariff. NTLE for these purposes must be determined by the cost of losses, taking into account the characteristics of the sources. The share of payment for losses in the networks of an TGO enterprise, which goes to its own consumption and is not compensated by sub-subscribers, is reduced. Consequently, the amount of costs for electricity and their share in the cost of finished products of the TGO enterprise is reduced.
