photovoltaic generation, power losses, load curve, form factorAbstract
The totality of technical, political, and environmental factors stimulates a relatively rapid growth of distributed solar power plants around the world. Integration of solar power plants into electric grids is one of the most topical aspects for further development of the power industry. At the same time, the development of photovoltaic generation entails an acute problem of its impact on the operating modes of distribution networks and relative power losses.
Power flow measurements in the electrical networks to which the solar panels of public health facilities in the city of Dushanbe, Tajikistan, are connected, were carried out. The effect of distributed photovoltaic generation on the power losses and on the load curve profile was analyzed. The analysis results have revealed that there is a problem of excessive photovoltaic generation at weekends, which results in that an active power flow from the consumer to the power system is produced, causing a change in the load curve profile and a growth of relative power losses. A calculation method is proposed that makes it possible to minimize the relative power losses in electric networks, thus resulting in achieving more efficient operation of the electric grid company under the conditions of using distributed photovoltaic generation.
