Abstract
During the operation of oil pipelines, accidents with oil spills may occur, which can cause severe damage to the ecological situation in the region and disrupt many processes in nature. The oil pipeline’s remote monitoring and control systems (RMCS) are used to prevent such situations. In areas remote from the centralized power supply, it is necessary to use a standalone power system (SPS) to provide electricity to RMCS facilities. Examples of such facilities are remote monitoring and control (RMC) stations, including systems for monitoring the state of the oil pipeline and its parameters, leak detection systems, and the pipeline’s cathodic protection. The paper proposes a methodology for sizing SPS with a photovoltaic plant, an on-pipe thermoelectric generator, and batteries for the power supply of the RMC station. The idea of the work is to use energy sources that are most efficient at opposite seasons of the year. Particle swarm optimization is used to optimize the sizing of SPS components. The technical optimization criterion is the loss of load probability. The economic optimization criterion is the levelized cost of electricity. The impact of the oil temperature at the point of the RMC station on the efficiency of the thermoelectric generator is estimated. The calculations carried out in this work were made for the climate region of the Vankorsk oil and gas field in the north of Russia. The methodology proposed in this paper can also be used for northern territories, such as Canada, Norway, and the USA.
