Abstract
A major portion of the global energy demand was likely to be fulfilled by an extensive supply of renewable power. Renewable energy outputs, on the other hand, are changeable due to the dynamic nature of their sources. The integration of these variable sources of power into current power grids is proving difficult for electrical power system operators all around the world. The fundamental issue with renewable energy systems is that, due to the stochastic nature of renewable power, electricity production varies from period to period. Recent research and development on renewable technologies can ensure the islands’ long-term electricity supply. Renewable energy sources, on the other hand, are limited by their unpredictable nature and significant reliance on weather conditions. To offset this disadvantage, several renewable energy sources and converters must be joined. To balance the power generation and load power, a hybrid renewable power generation for standalone application is proposed. The solar plant model is made up of a 170 W photovoltaic (PV) panel connected in series, and conversion of energy is done using the maximum power point tracking (MPPT) algorithm, which regulates a buck-boost converter modulation. The MPPT method used in the converter’s control step is based on perturb and observe (P&O) and enhanced with a PI controller. The bidirectional buck-boost DC-DC converters (BBDC) are utilized to preserve a DC-link voltage stable. This is also storing additional hybrid energy in a large battery and is distributed to the system load; then there is a shortage of hybrid power. The load current power is regulated in terms of the frequency and enables it to be achieved using three vector control technique voltage source inverters (VSI). The results were offered to demonstrate a hybrid performance of this organization.
Highlights
Hybrid renewable power generation is becoming increasingly versatile and appealing to meet load in both standalone and grid-connected modes
The proposed system involves of a PV system, a pulse width modulation (PWM), an Oscillating Wave Column (OWC) scheme, a buck-boost DC-DC converters (BBDC) with even a proportional-integral-derivative (PI) ratio of control duty, a storage battery, and insulated-gate bipolar transistor (IGBT) voltage source inverters (VSI) located on the demand side [13]
The PV-renewable and wave-energy systems are employed as the major power generating source to satisfy systems demand requirement in hybrid renewable energy source (HRES), while stored energy is being used as a standby energy storage system
Summary
Hybrid renewable power generation is becoming increasingly versatile and appealing to meet load in both standalone and grid-connected modes. The predictable power generation resources were finite and will be consumed in the years [1]. In the current context of increased power generation needs, leading to the advancements of sophisticated digital technology and a much more pleasant lifestyle, it is critical to produce more energy to close a significant gap between generation and transmission requirements. When the system has a power shortage, embedded production in distribution systems compensates for it. Fossil fuels presently account for the majority of the world’s energy sources
