Abstract

Penerapan Power Wheeling memerlukan rancangan tarif yang mampu menjamin pemulihan biaya sekaligus mendorong investasi dan efisiensi pasar.Penelitian ini mengusulkan Model Tarif Hybrid yang mengintegrasikan metode Postage Stamp sebagai tarif dasar dengan komponen Locational Marginal Price(LMP) yang diterapkan dalam bentuk Zonal Adjustment Tariff (ZAT). Simulasi dilakukan menggunakan AC Optimal Power Flow (AC OPF) pada sistem IEEE 30-bus yang dimodifikasi dengan penyebaran panel surya (PV) untuk merepresentasikan kondisi operasi yang lebih realistis. Model ini menghasilkan tarif dasar sebesar 76,36 USD/MWh, komponen biaya pembangkitan 23,96 USD/MWh, dan total pemulihan biaya tahunan sebesar 166,28 juta USD. Melalui kerangka FTR-LMP dan metode K-Means Clustering, sistem terbagi menjadi tiga zona dengan tarif masing-masing 106,03; 101,36; dan 88,88 USD/MWh. Struktur zonal tersebut memberikan sinyal lokasional yang jelas, akni zona bertarif tinggi mengindikasikan area dengan potensi kongesti, sedangkan zona bertarif rendah menawarkan insentif bagi ekspansi beban maupun investasi pembangkit. Analisis sensitivitas terhadap variasi beban dan suplai menunjukkan bahwa rancangan tarif tetap stabil terhadap perubahan sistem, dan mempertahankan revenue neutrality. Secara keseluruhan, model tarif hybrid ini menawarkan pendekatan berbasis data yang praktis, transparan, dan berkelanjutan untuk perancangan tarif Power Wheeling yang seimbang secara ekonomi.

The implementation of Power Wheeling requires a tariff design that ensures full cost recovery while simultaneously promoting investment and market efficiency. This study proposes a Hybrid Tariff Model that integrates the fixed-rate Postage Stamp method with the dynamic Locational Marginal Price (LMP) component, applied as a Zonal Adjustment Tariff (ZAT). The simulation is carried out using AC Optimal Power Flow (AC OPF) on a modified IEEE 30-bus system with distributed PV generation to represent a realistic Power Wheeling scenario. The proposed model yields a base Postage Stamp tariff of 76.36 USD/MWh and a generation cost of 23.96 USD/MWh, ensuring an annual cost recovery of 166.28 million USD. Through the FTR-LMP framework and K-Means clustering, the system is divided into three zones with resulting tariffs of 106.03, 101.36, and 88.88 USD/MWh. These zonal tariffs provide clear locational signals: higher tariffs indicate congestion and discourage load expansion, while lower tariffs attract new generation investments. Sensitivity analysis under ±10% load variation confirms the stability of the tariff, demonstrating resilience to system changes while maintaining revenue neutrality. By combining cost recovery with economic efficiency, the hybrid model not only allocates transmission costs fairly but also delivers actionable operational and investment signals for market participants and independent power producers. Overall, this study offers a practical, data-driven framework for designing transparent, sustainable, and economically balanced Power Wheeling tariffs.
