Addition of the Guluk-Guluk Substation, it will affect the flow of power and voltage in the electric power system. Based on the analysis of normal conditions before and after the Guluk-Guluk Substation in terms of the voltage value on each connected bus, it is still within the permitted limits, while the contingency ranking calculation using the Voltage Performance Index (PIv) method can determine contingency conditions N-1 to N -3 before and after the Guluk-Guluk Substation. In this case, it was found that during the contingency conditions N-1 to N-3 before the Guluk-Guluk Substation there was a decrease in the value of the voltage which was still within the permissible limits, but in the N-3 contingency there was also an overload on the line due to the release of two generator units and one channel. After the existence of the Guluk-Guluk Substation, during the N-1 to N-2 contingency conditions the voltage value was still within the permissible limits, but the voltage drop that occurred was bigger than the condition before the Guluk-Guluk Substation. For the N-3 contingency condition the voltage value does not meet the standard due to overload on the Ujung Substation - Bangkalan Substation line and the lack of power flow.

Provision of quality and sufficient electrical energy is something that must be done by PT. PLN (Persero). Based on data from PT. PLN (Persero), carried out work on replacing conductors on the Paiton – Kraksaan – Probolinggo transmission line from the TACSR 330 mm2 conductor with KHA 1190 A to 2xACCC/TW Copenhagen with KHA 2016 A. Reconductoring work is one of the efforts to uprating the transmission line by considering increasing load requirements. This reconductoring is carried out using the open circuit method or a total blackout in a circuit where the conductor is being replaced by taking into account the stages determined by PT. PLN (Persero). So that the power flow in the system must be considered when these conditions take place for the sake of service reliability or system reliability using a power flow simulator application, namely ETAP software. The simulation voltage tolerance with actual conditions is 5%. Next, analyze the power flow on the affected transmission line which is directly connected to the Kraksaan – Paiton – Probolinggo 150 kV transmission line based on voltage drop, transmission line losses and loading from each stage. As well as calculating the power transfer capability after and before reconductoring. The results of the simulation show that the most significant anomaly (deviation that should not be) is that there is a critical point loading of up to 89.220% on the Probolinggo - Gondangwetan channel when reconductoring has been carried out except for the Paiton - Kraksaan1 transmission line. Meanwhile, the value of power transfer capability increased after reconductoring, where the Paiton-Kraksaan1 and Paiton-Kraksaan2 channels increased by 63.91 MW, the Kraksaan - Probolinggo1 channel increased by 67.95 MW, and the Kraksaan - Probolinggo2 channel increased by 63.461 MW from previously

In this new era the use of Photovoltaic (PV) is increasingly being used as an energy source. However, this technology has a drawback, namely, the intensity of the sun's light is always changing every time. This can cause the output voltage of the Photovoltaic (PV) Cell to be variable or indeterminate. In the Photovoltaic (PV) Cell, a dc-dc converter circuit is needed which functions to regulate and change the output of the Photovoltaic (PV) Cell. Conventional DC-DC boost converters are unable to provide a high step-up voltage boost due to the effects of switching power, rectifier diodes, and equivalent series resistance of inductors and capacitors. In this study, a closed loop design using a PID controller and analysis of a non-isolated boost dc-dc converter based voltage lift technique were carried out to achieve a high step-up voltage gain. In the presented converter two inductors, three capacitors and three power diodes are used. From this structure, this converter is referred to as a voltage lift cell-based boost converter. The structure of the presented converter is considered very simple, since it has only two stages of power. The voltage and current equations of each element with the converter voltage gain under continuous conduction mode (CCM) were extracted. In addition, the steady state analysis of the amplified stress and boundary conditions is discussed in this study. This boost converter circuit is simulated through the PSIM application. From the simulation results in the PSIM application, it is found that the boost converter circuit is able to increase the voltage from 100 V to 400 V and has an error value of 0. The specifications of the simulation results are a duty cycle of 0.6, and a frequency of 10,000 Hz.

One type of power converter that is widely applied in the field of renewable energy is DC-DC Converter. In variousapplication cases, voltage control features are often required. One of the challenges is how to build a closed loop controller to control the output voltage of the DC-DC Converter. In this journal, an Arduino Mega based output voltage controller will be implemented. The type of voltage controller implemented is the PI controller with the consideration that the controller has been well-known tested and mathematically proven. The PI controller is set based on closed loop block diagram calculations with the Buck Converter as the main plant. The implementation of the PI controller on the Arduino Mega is based on the expected transient response settings. PI controller was successfully implemented in this study. The experimental results show that, the controller can maintain its voltage along with changes, both source and load voltage. Thus, it can be concluded that the Arduino Mega board can work well in closed loop applications for power converter control.
