Biodiesel is a promising renewable energy source due to its comparable properties with petroleum diesel and is reported to be friendly environmental. One way to prepare affordable biodiesel is through the transesterification of waste cooking oil. Utilization of biodiesel from waste cooking oil need low cost of production and give a great profit. This paper aims to investigate the synthesis of biodiesel using potassium hydroxide catalyzed transesterification of waste cooking oil in a continuously stirred thank reactor and the performance evaluation of biodiesel-petroleum diesel blend to fuel an unmodified diesel engine. The optimum conditions for the transesterification were at 60 o C using a catalyst loading of 2% wt. of waste cooking oil. The biodiesel obtained from this work has met the existing Indonesian regulatory standards for biodiesel. Based on the consumption, acceleration, and opacity tests, up to 10% volume substitution of petroleum diesel with biodiesel can satisfactorily fuel diesel engines without modification.

A new statistical fault detection method is proposed in this paper to detect the faults in the distribution lines connected with wind farms. The approach is designed with the help of symmetrical nature of current signals during normal conditions of the system to detect the faults using the non-linearity segment. For this purpose, statistical mean of 1/4 th cycle of current information is used with shifting window mechanism. The method utilize direct instantaneous signal information reduces the computational burden and increases the speed of the decision. The method is tested on wide class of unsymmetrical and symmetrical faults with different fault parameters. The influence of the location, inception angle and resistance of the faults are simulated to test the efficacy of the proposed method. Further, the investigations of the proposed methods are extended to variable wind system conditions to check the adaptability of the method. All the simulations are carried out on a 25 kV, 9 MW wind farm connected to grid using MATLAB-SIMULINK.

Renewable energies offer many benefits in reducing the harm and consequences caused by conventional resources such as fossil fuels. However, the high penetration of renewable energy sources presents a challenge for the operation and stabilization of system frequencies because of the uncertainties of weather factors. Moreover, the renewable energy operation does not participate in the process of supporting the inertia of the whole system. Therefore, the paper proposes a combined strategy including storage system and deloading operation to support system frequencies in microgrids to improve operational efficiency. By creating an additional amount of reserve capacity to mobilize in time in case of an imbalance of power, thereby helping to stabilize the frequency. The proposed suggestion has been evaluated in Matlab/Simulink software in multiple cases to show the effectiveness.
