It is particularly attractive because of its abundance, renewability, cleanliness and its environmentally-friendly nature. One of the important technologies of solar energy is photovoltaic (PV) technology which converts irradiation directly to electricity by the PV effect. However, it can be realized that the solar PV panels have a few disadvantages such as low conversion efficiency (9% to 17%) and effects of various weather conditions [1]. In order to overcome these issues, the materials used in solar panel manufacturing as well as collection approaches need to be improved. Obviously, it is particularly difficult to make considerable improvements in the materials used in the solar PV panels.
Abstract - This paper proposes a versatile and ideal
control procedure for a sunlight based photovoltaic (PV) framework. The control procedure guarantees that the sun based PV board is generally opposite to daylight and all the while worked at its most extreme power point (MPP) for constantly reaping greatest power. A mixture control technique for a PV and battery energy capacity framework (BESS) in an independent dc MG is proposed in this paper. Rather than the traditional control methodologies that manage the dc-interface voltage just with the BESS, the proposed control procedure takes advantage of both the PV framework and the BESS to direct the dc-connect voltage. The proposed control methodology is the control blend between the solar powered trackers (ST) and (MPPT) that can enormously work on the produced power from sun based PV frameworks. As to ST framework, the paper presents two drive approaches including shut circle drives. The paper likewise proposes Incremental conductance (InC) calculation for improving the speed of the MPP following of a sun oriented PV board under different climatic circumstances as well as ensuring that the working point generally moves towards the MPP utilizing this proposed calculation. The viability of the proposed control methodology on delaying the lifetime of a lithium-particle battery and a lead-corrosive battery is examined through a reenactment contextual investigation with one-day burden and irradiance bend profiles.
Renewable energy resources are rapidly replacing conventional fuels to generate electricity in order to achieve energy sustainability, and reduce the carbon footprint [1]. Solar energy is one of the most abundantly available renewable resources and hence, photovoltaic (PV) power generation share is steadily increasing. DC microgrid (dcMG) power systems are drawing great attention due to the steady growth in dc load demand and renewable dc sources. The majority of modern consumer electronics such as energyefficient lighting systems and energy-saving electronics are operated with dc supply. Furthermore, PV modules and batteries are intrinsically dc components. Therefore, by using a dcMG to transfer power from dc sources to dc loads would eliminate the necessity of having dc-to-ac conversion stages on the generation side and ac-to-dc conversion stages on the load side. Also, synchronization and reactive power flow issues are null in dcMGs [2], [3]. Such dc systems are used in a broad range of applications including ships, automobiles, telecommunication stations, etc. However, issues associated with dynamically changing weather conditions and dc-link voltage transients may lead to instability in the microgrid and hence, dcMGs require a robust control scheme. The majority of existing PV controllers aim to extract the maximum power from the PV arrays using maximum power point tracking (MPPT)
Key Words: Battery energy storage system (BESS), battery state-of-charge (SoC), dc microgrid (dc MG), improved incremental conductance power point tracking (InCPPT) algorithm photovoltaic (PV).
1. INTRODUCTION Energy is absolutely essential for our life and demand has greatly increased worldwide in recent years. The research efforts in moving towards renewable energy can solve these issues. Compared to conventional fossil fuel energy sources, renewable energy sources have the following major advantages: they are sustainable, never going to run out, free and non-polluting. Renewable energy is the energy
