Indonesia is geographically located on the equator, which has very strong solar radiation and high rainfall, making it suitable for farming. Hydroponics is used as a growing medium for planting without using large areas of land by utilizing water and prioritizing the nutritional needs of plants. NFT is a hydroponic method that is easy to implement and is quite effective for plants. However, this method requires a cycle that cannot be stopped, so it requires a pump that must be on all the time. Therefore, a backup supply is needed that can guarantee the availability or continuity of the supply of electricity to the load by using an Automatic Transfer Switch (ATS) which keeps the system running if the PLN goes out by using PLTS and can be monitored and controlled at any time using Internet of things (IoT) technology. ). From the results of trials and analysis carried out that the performance of the system when in automatic mode, that is, when the battery reaches a value of 11.3 Volts, it will switch to the PLN supply. The supply from PLTS will change to PLN's supply automatically with a predetermined time, namely from 09.00 WIB to 15.00 WIB. If PLN experiences a blackout, it will switch to the PLTS source until PLN is back on.

The current transformer is an electric power instrumentation device that functions to change a higher current value to a lower value for protection and measurement purposes. Field conditions and service life cause the current transformer to decrease and not function. Therefore, it is important to do this research to determine the current condition of the current transformer. The method used to obtain current transformer quality indicators is the insulation resistance test method and the tangent delta test method. The results of testing the insulation resistance of current transformers at GI Tanjung Awar Awar Babat in 2020-2021 using the VDE standard (Catalogue 228/4) and IEEE std 43-2000 show that the insulation resistance value of all current transformers has increased by an average of 81900Ω from the previous period but, this value is still in good criteria, namely 170 + 1 MΩ and there is an increase in the current transformer grounding resistance test from the previous period with an average of 0.176 however, according to the PLN book 605.K/DIR/2010 the results of the ground resistance test have good criteria. of < 1. Based on ANSI C 57.12.90 and IEEE C57.152-2013 standards, the tan delta test results are still in good condition because the tan delta value is not more than 0.5%. Current transformer tan delta testing in 2020-2021 has decreased, indicating that the insulation performance of current transformers in 2021 is better than in 2020.

The tendency for the price of using solar PV (photovoltaic) to become cheaper means that the portion of the use of this solar energy source is encouraged to be larger along with the addition of the portion of renewable energy (EBT) generators based on PLN's 2021-2030 Electricity Supply Business Plan (RUPTL). As a step to mitigate this problem, a power electronics circuit application is needed in the form of a boost converter or what can be called a step-up DC-DC converter. In this study, the boost converter design modeling is made a closed loop. There is feedback by adding a PID controller to adjust the duty cycle as a function of switching on or off MOSFET so that the output voltage is as desired (setpoint) and adjusts to needs of load. Open-loop design modeling is also included as a comparison. The design stage begins with determining the circuit design, calculating component specifications, and simulating using MATLAB R2013a software and hardware implementation. From the test results, it was found that the boost converter can increase the solar PV voltage varies (17.34-19.13 Volts). In the closed loop boost converter circuit with a constant load of 129.96 Ω with varying duty-cycle value set by PID controller with value of Kp=0.005 Ki=9.75 Kd=0.00000029, the average output voltage is 36. 0067 Volts and stable at the desired setpoint of 36 Volts.

Electrical energy generated also comes from several energy, namely water, steam, nuclear, etc. In Indonesia the type ofsteam power plant is a type of power plant that is widely used, where one of the crucial problems that are often encountered in this generation system, namely the problem of stability. The stability of the electric power system is the ability of the system to return to normal or steady operation after a large load load switching or interference. Disruption or load switching that exist in the system must be muted and aligned in a certain time to be said to be stable. Causes of instability are disruptions in the form of large capacity load switching, and the type of interference. One aspect that affects the stability itself is the transient stability. The transient stability is related to the sudden influx of large-capacity loads and affect the performance of the generator, therefore it is necessary to analyze the voltage and frequency transient stability for the evaluation of the capability of the electrical system so that the system maintains the continuity of the supply of electrical energy to the load normally. Based on the research results, the current flowing before the disturbance of 98.9 A and current disturbance of 145.2 kA. This causes the voltage response to decrease 50% of the nominal, and the frequency increases to 50.36 Hz. The time required from the disturbance condition to a stable condition within 5 seconds.
