    Optimal grid-connected tariff of wind energy conversion systems for Malaysia
    (Universiti Malaysia Terengganu, 2017-07) Aliashim Albani
    The growing interest in wind energy in Malaysia is driven primarily by the government’s aspiration in achieving the national target on renewable energy generation capacity. Hence, prior to embarking a commercial wind energy project in Malaysia, a detailed study should be conducted on the potential of wind resources and identification of appropriate policy. The designed policy should take into account the quality of the local wind speed and existing renewable energy incentives in Malaysia. This study predominantly aims for identifying the best policy framework model that suits the wind energy condition in Malaysia. Therefore, to accomplish this goal, the research endeavours the evaluation of potential wind resources based on three aspects, namely (i) installation of wind masts, measurement and analysis of primary wind data, (ii) establishing wind-related models that accomodate Malaysia’s scenario, and (iii) derivation of a closed-form equation and determination of the best tariff rates and remuneration models. Initially, the iv dependence of power law indexes on surface temperature and terrain types was studied as they are associated with the form of exponential fits. Next, the wind turbine ranking method was improved by incorporating the crucial factors such as height restriction law, wind park capacity target and wake losses into the recent wind turbine ranking framework method. Finally, the optimal tariff modelling was carried out by deriving the generation-cost-based tariff rate determination model, front-loaded remuneration models, and tariff rate differentiation for implementation in Malaysia. The sensitivity analyses were employed to determine the impact of several factors such as the investment costs, discounting rates, debt and equity share, debt interest rates, and capital allowance.

    Wind energy assessment for selected sites in Malaysia and the proposed feed-in-tariff rates
    (Terengganu: Universiti Malaysia Terengganu, 2013-11) Aliashim Albani
    Wind energy is still not recognized as eligible energy resource in Malaysian Renewable Energy Act 2011. There are only four technologies applicable for Feedin-Tariff (FiT) which are biomass, biogas, solar and small hydro. Thus, there is no Feed-in-Tariff (FiT) for the wind projects in Malaysia. This thesis presents the identification of Feed-in-Tariff (FiT) based on the Annual Energy Production (AEP) at every selected site: Kuala Terengganu, Mersing, Kudat and Langkawi Island. WindPRO and WAsP software are used for the energy simulation. The wind data are obtained from the Malaysian Meteorological Department (MMD) stations. The Pitch 22 kW wind turbine was selected for energy simulation due to its best capacity factor compared to the other type of wind turbines. Forty six different installed capacity wind farm in range 22 kW till 1.012 MW were simulated based on the 22 kW wind turbine, sites roughness condition and sites wind resources. The Feed-in-Tariff (FiT) is identified by Net Present Value (NPV) analysis, Payback Period (PBP) analysis and degression rate analysis. The result found that the proposed FiT rates are based on the value of NPV is 98.6% from the investment cost with payback period is 10 years. The best degression rate is 5% for every year.
