Intisari—Provinsi Bali adalah salah satu dari 34 provinsi di Indonesia dan menurut Rencana Umum Energi Nasional diharapkan untuk mengembangkan sekitar 110 MW solar PV pada tahun 2025. Secara ekonomi, Bali dianggap sebagai pusat industri pariwisata Indonesia. Berbagai akomodasi telah dikembangkan untuk mendukung industri termasuk villa. Dalam tulisan ini, potensi Rooftop PV pada villa di Bali disajikan. Kapasitas Rooftop PV dirancang dengan tujuan untuk memenuhi 23% dari konsumsi energi villa. Dua villa di Bali selatan diambil sebagai contoh. Audit energi dilakukan untuk mempelajari penggunaan energi kedua villa. Berdasarkan tujuan desain, 13,7 kWp PV yang terhubung ke jaringan diusulkan untuk masing-masing villa. Dengan hasil ini, diproyeksikan bahwa semua villa di Bali dapat menambah kapasitas solar PV sekitar 34,8 MWp yang berpotensi menghasilkan energi tahunan 54.741 MWh. Analisis investasi dan kinerja lingkungan juga dimasukkan dalam makalah ini. Hasil yang disajikan di sini akan membantu pemerintah provinsi dan kabupaten di Bali untuk mendapatkan wawasan tentang potensi sektor pariwisata untuk mendukung pengembangan PV dan selanjutnya mengembangkan kebijakan dan peraturan yang sesuai untuk mempercepat penyerapan Rooftop PV di Bali. Kata Kunci — Energi terbarukan, Rooftop PV,Grid-connected, Pengurangan emisi, Pariwisata hijau.

Solar Photovoltaic (PV) systems have been in use predominantly since the last decade. Inverter fed PV grid topologies are being used prominently to meet power requirements and to insert renewable forms of energy into power grids. At present, coping with growing electricity demands is a major challenge. This paper presents a detailed review of topological advancements in PV-Grid Tied Inverters along with the advantages, disadvantages and main features of each. The different types of inverters used in the literature in this context are presented. Reactive power is one of the ancillary services provided by PV. It is recommended that reactive power from the inverter to grid be injected for reactive power compensation in localized networks. This practice is being implemented in many countries, and researchers have been trying to find an optimal way of injecting reactive power into grids considering grid codes and requirements. Keeping in mind the importance of grid codes and standards, a review of grid integration, the popular configurations available in literature, Synchronization methods and standards is presented, citing the key features of each kind. For successful integration with a grid, coordination between the support devices used for reactive power compensation and their optimal reactive power capacity is important for stability in grid power. Hence, the most important and recommended intelligent algorithms for the optimization and proper coordination are peer reviewed and presented. Thus, an overview of Solar PV energy-fed inverters connected to the grid is presented in this paper, which can serve as a guide for researchers and policymakers.

The Impact

As the unconstrained integration of distributed photovoltaic (PV) power into a power grid will cause changes in the power flow of the distribution network, voltage deviation, voltage fluctuation, and so on, system operators focus on how to determine and improve the integration capacity of PV power rationally. By giving full consideration to the static security index constraints and voltage fluctuation, this paper proposes a maximum integration capacity optimization model of the PV power, according to different power factors for the PV power. Moreover, the proposed research analyzes the large-scale PV grid access capacity, PV access point, and multi-PV power plant output, by probability density distribution, sensitivity analysis, standard deviation analysis, and over-limit probability analysis. Furthermore, this paper establishes accessible capacity maximization problems from the Institute of Electrical and Electronics Engineers (IEEE) standard node system and power system analysis theory for PV power sources with constraints of voltage fluctuations. A MATLAB R2017B simulator is used for the performance analysis and evaluation of the proposed work. Through the simulation of the IEEE 33-node system, the integration capacity range of the PV power is analyzed, and the maximum integration capacity of the PV power at each node is calculated, providing a rational decision-making scheme for the planning of integrating the distributed PV power into a small-scale power grid. The results indicate that the fluctuations and limit violation probabilities of the power system voltage and load flow increase with the addition of the PV capacity. Moreover, the power loss and PV penetration level are influenced by grid-connected spots, and the impact of PV on the load flow is directional.

<p>The abundance of solar energy in Akure, South-West Nigeria and its feasibility as an alternative energy source has been proven. However, cheap, Government subsidized but unreliable grid electricity and high cost of solar equipment are considered the major hindrances to deployment of solar energy for improved power supply and environmental sustainability. An earlier work pointed out realistic pricing of electricity, reduced cost of solar equipment and reduction in solar cell degradation factor as major factors capable of speeding up parity hence, motivating solar energy consumption. It showed that parity is attainable within 14 years. Documented significant improvements in these factors in recent times are the motivations for this review. This review cost-comparatively re-assesses both sources of energy under the prevailing National electricity policy and market realities using simple mathematical and graphical modeling techniques. This is with a view to determining a new timing for parity of solar energy with grid supply. Results showed that solar PV-grid energy cost parity is now attainable within 6 years in the study region. It was also observed that sustained improvement in grid energy unit cost and reduction in cost of solar equipment and accessories may accelerate solar-grid energy parity to less than three years.</p>
