  • Intermittent Renewable Energy Source (IRES) model of solar Energy in Cipayung microgrid system
    Journal of Physics: Conference Series, 2019
    Co-Authors: Handrea Bernando Tambunan, Putu Agus Aditya Pramana, Buyung Sofiarto Munir
    Abstract:

    Indonesia has a great solar Energy potential because its location is in a tropical area. One significant characteristic of solar Energy is intermittent. Integration of intermittent Renewable Energy Source (IRES) especially solar Energy into electrical power grid can cause significant impact in power system stability. This study aims to model the IRES characteristic, profile, and time duration classification based on collected data in Cipayung microgrid system. The result shows the characteristic of IRES consist of two things, a sudden increase and suddenly decrease of solar Source. These characteristic profile model is made by a polynomial and logarithmic regression analysis using mathematical equation. A condition where the availability of solar Energy is immediately at a maximum or at a lowest point of zero has never been found. The very fast IRES classification occurs the most often with 0.5 to 1.0 minutes of time duration. System operator can use this information to prevent the system from collapsing and even having a blackout.

  • Maximum Allowable Intermittent Renewable Energy Source Penetration in Java-Bali Power System
    2018 10th International Conference on Information Technology and Electrical Engineering (ICITEE), 2018
    Co-Authors: Handrea Bernando Tambunan, Aristo Adi Kusuma, Buyung Sofiarto Munir
    Abstract:

    The significant characteristic of Renewable Energy Source especially solar and wind is intermittency. It could cause significant impact on power system stability and reliability. This study was conducted to estimate maximum allowable penetration of intermittent Renewable Energy Source (IRES) where frequency and voltage must meet the stability and reliability requirement of the electric power system. The worst possible scenario that may occur in the system was used, such as penetration in weakest bus by sensitivity analysis, dry season, one time sudden loss of largest generator and IRES generation, and peak load and off-peak load condition. The result showed IRES penetration level into the Java-Bali power system using 2017 scenario in peak load is about 0.83% while in off-peak load is about 0.44% from total available generation in current condition without any action taken to compensate the penetration.

    Co-Authors: Handrea Bernando Tambunan, Kevin Gausultan H. Mangunkusumo, Brian Bramantyo S.d.a. Harsono, Arionmaro Asi Simaremare, Nur Widi Priambodo, Buyung Sofiarto Munir
    Abstract:

    Bangka is an island in Indonesia that have potential for the utilization of renvewable Energy. One of the challenge using Renewable Energy Source is intermittency characteristic. It will have a considerable impact on power system stability and reliability. The scenario aim to calculate how much intermittent Renewable Energy Source (IRES) penetration level into the interconnected power system without causing frequency and voltage collapse based on applicable standards. The penetration level based on the worst scenario that may occur in the system during intermittency such as penetration in weak bus, dry season, maintenance of largest generator, peak load, and off-peak load condition. The result showed the IRES penetration level into the Bangka power system in off-peak load is about 0,01% but in peak load need to prepare spinning reserve with high possible ramp rates.

This study aims to calculate how much intermittent Renewable Energy Source (IRES) penetration into the interconnected power system without causing collapse the system based on applicable standards. Stable conditions by standards must meet the acceptable voltage and system frequency. The level of IRES penetration based on the worst scenario that may occur in the system during intermittent such as penetration in weakest bus by sensitivity analysis, dry season, maintenance of largest generator, peak load, and off-peak load condition. The simulation showed the IRES penetration level into the South of Sulawesi power system are about 0,32% in off-peak load and about 5,24 % in peak load.

    2018 2nd Borneo International Conference on Applied Mathematics and Engineering (BICAME), 2018
    Co-Authors: Dhandis R. Jintaka, Handrea Bernando Tambunan, Brian Bramantyo S.d.a. Harsono, Joko Hartono, M H S Kemas Tofani, Buyung Sofiarto Munir
    Abstract:

    West Kalimantan is an island in Indonesia that has a great opportunity to integrate the Renewable Energy such as solar PV and wind to the existing grid. One significant nature of using these Renewable Energy is intermittency. The intermittent Renewable Energy Source (IRES) penetration level to the West Kalimantan Grid can cause significant impact on frequency and voltage stability. This condition could bring the system to experience worst condition even blackout. IRES penetration based on worst case scenario in peak load hours and off-peak load hours, dry season, loss of largest generation, and penetration in most sensitive bus was simulated by considering the frequency and voltage limit. The simulation result showed the IRES penetration level into the West Kalimantan grid are approximately 16,00% in peak load hours and 7,98% in off-peak load hours.

  • Power quality improvement using STATCOM with Renewable Energy Sources
    2012 IEEE 5th India International Conference on Power Electronics (IICPE), 2012
    Co-Authors: Kaliappan Ilango, A. Trivikram, Guntipally Mounika, Atul Bhargav, P.s. Kavya, Manjula G. Nair
    Abstract:

    The Renewable Energy Sources play an important role in electric power generation with growing environmental concerns. The inter connection of Renewable Energy Sources are incorporated using power electronics converters, with the aim of improving power quality at the point of common coupling (PCC). This paper presents a novel idea where a STATCOM is used innovatively as a load reactive power compensator an interface unit between the grid and Renewable Energy Source, and as an effective method for real power exchange between the dynamic load system, grid and Renewable Energy Source. A controller unit is proposed for the STATCOM based on modified Icosf algorithm by which reactive power compensation and power factor correction is done and also real power support is provided by Renewable Energy Source through STATCOM. The performance of the proposed algorithm is compared with the modified Instantaneous Reactive Power Theory (IRPT) control algorithm to achieve the above objectives.
