Stochastic Approaches for Economic-Technical-Environmental Operation of Microgrids with Different Energy Storage Systems Considering Uncertainty of Parameters

Today’s power systems are characterized by a large percentage of electricity production from renewable energy sources. However, renewable energy sources are characterized by n...non-stationary production, which leads to more complicated regulation of voltage, power flows, and frequency in the power system. Energy storage systems (ESSs) have been identified as one of the more efficient solutions to overcome some of these problems. However, in previous scientific researches, ESSs have been predominantly viewed only as producers or consumers of active power. In the available literature, it is possible to find a description of certain types of electricity storage systems from different aspects – historical, technical characteristics, applications, and others. It is important to emphasize that there are different types of electricity storage systems–reversible hydropower plants, compressed air systems, battery energy storage systems, flywheels, SMES, supercapacitors and others. In addition to the aforementioned function, ESSs are also used to reduce the cost of electricity production, reduce CO2 emissions, regulate frequency, improve power factors, etc. In this project, the main aim is to study renewables’ penetration and energy alternatives in modern power systems to enhance their usage through the optimal selection and allocation of energy storage systems. Research on the most suitable storage system for different applications will be investigated. Also, in KSA, ESS techniques are still missing keys in energy policies, and unfortunately, energy storage plans are not appropriately incentivized or supported. Consequently, this project will address the various types of ESSs and examine their impact on renewables penetration enhancement.
