Abstract

The relevance of the transition from traditional to renewable energy sources is investigated in the paper. The most popular renewable energy sources (RES) for Ukraine and the World are highlighted. The trend of changing electricity generation by photovoltaic stations is analyzed. Peculiarities of the functioning of electric networks with RES are considered. A mathematical model of the problem of optimal control of the parameters of the normal mode of the power system (PS) with a high level of integration of photovoltaic power plants (PPS) is presented. The main components of the criterion of optimality in the control of the power system, which must be taken into account when determining it. The article investigates in more detail such a component of the optimality criterion as power equivalent to the loss due to power failure caused by unstable generation. The instability of RES generation, in particular, FES, can be caused by both unpredictable changes in meteorological factors and changes in the technical condition of FES equipment. The photovoltaic module is the main element of any FES, so the article focuses on determining the technical condition of the FEM. Therefore, the main study presented in the article is the development of a neuro-fuzzy model to determine the technical condition of the FEM, which is represented by the coefficient of the total residual resource. For this purpose, the characteristic fault to the FEM, in particular, the fault to the frame of the FEM is analyzed and presented; the fault to cable insulation; the consequences of increasing resistance and heating of the contacts at the junction of the cell busbar FEM; the decrease to the impermeability of the FEM and others.
