Justification of preliminary sizing and interconnection scheme for a distributed generation unit serving an area with abnormal power demand

   The article examines the problem of the justification of preliminary sizing and interconnection scheme for a distributed generation unit serving an area with abnormal power demand relative to the normative level. The research extends the previously completed stage of interval estimation of the technocenosis of municipal entities within the Prokopyevsky district of the Kemerovo Region (Kuzbass). The paper is dedicated to the subsequent optimization phase: the identification of the anomalous object, the normalization of its specific electricity consumption, and a preliminary engineering assessment of the local generating unit's
capacity.

   The object of the research is the Mayakovka village in the Kemerovo Region (Kuzbass).

   The authors perform the comparison of actual versus normalized specific electricity consumption basing on a continuous dataset spanning 48 months. The average magnitude by which actual values exceed the normative baseline is determined. It is shown that the equivalent average power of a compensating source amounts to approximately 28 kW; however, for more stable compensation of the additional energy demand, it is advisable to consider a preliminary design range for the installed capacity of 32–70 kW. The research substantiates an operating scheme for the local generation unit in parallel with the centralized grid, wherein the external network serves as the primary reserve. The results can be applied in the preliminary selection of distributed generation parameters for other rural areas with abnormal electricity consumption.
