“…The connection between droop gain and load power is linear. Droop gain is altered dynamically as the load power changes in this technology [10]. The adaptive droop approach is used to build the principal control for each unit solely by utilizing local electrical parameters, which may re-duce both the control structure complexity and communication reliance in a practical power system.…”

A DC microgrid is an efficient way to combine diverse sources; conventional droop control is unable to achieve both accurate current sharing and required voltage regulation. This paper provides a new adaptive control approach for DC microgrid applications that satisfies both accurate current sharing and appropriate voltage regulation depending on the loading state. As the load increases in parallel, so do the output currents of the distributed generating units, and correct current sharing is necessary under severe load conditions. The suggested control approach raises the equivalent droop gains as the load level increases in parallel and provides accurate current sharing. The droop parameters were checked online and changed using the principal current sharing loops to reduce the variation in load current sharing, and the second loop also transferred the droop lines to eliminate DC microgrid bus voltage fluctuation in the adaptive droop controller, which is different and inventive. The proposed algorithm is tested using a variety of input voltages and load resistances. This work assesses the performance and stability of the suggested method using a linearized model and verifies the results using an acceptable model created in MATLAB/SIMULINK Software Version 9.3 and using Real-Time Simulation Fundamentals and hardware-based experimentation.

“…Therefore, it need a DC-DC Converter that can convert a variable DC voltage into a constant DC voltage, one of the DC-DC Converter circuits is the Buck Converter. Buck Converter is used to convert a higher input voltage into a lower output voltage [7]- [9]. Recently, there are several techniques that have been used to produce a stable output voltage on the DC-DC Converter such as fuzzy logic control [10]- [12], fuzzy Takagi-Sugeno [13] and PID [14].…”

Nowadays, energy sources in the world at the end until now tends to be filled using fossil fuels. It is estimated that the world energy consumption until 2025 is still dominated by fossil fuels, namely oil, natural gas and coal. The Ministry of Energy and Mineral Resources said that petroleum dominates 54% of energy use in Indonesia. One way to overcome the use of fossil energy sources is to replace them with renewable energy especially photovoltaic. Therefore, this paper presents solar charge system using Buck Converter PID Controller for Spotlight load. Buck Converter with PID Controller is used to produce a smaller and more stable output voltage from solar panels of 14.4 Volts for charging the battery. The PID parameter values ??obtained after performing calculations using the Analytic Tuning method and tuning are Kp = 0.0307, ??Ki = 58.20 and Kd = 0.000263. The expected result of this research is to design and implement a solar charge controller as a producer of electrical energy from environmentally friendly energy.

“…For the system to become more reliable overall, planning and protection must be well coordinated. Two primary reasons for this necessity are the erratic nature of renewable energy supply and the dynamic load profiles [17]. Figure 1 shows a DC microgrid consisting of DC-DC converters in the parallel buck-boost converter configuration.…”

To enhance the stability and reliability of the system, the converters' parallel operation can be cascaded to address the constraints posed by the substantial integration of renewable resources. Buckboost DC-DC converters are often controlled via a cascaded control approach to allow parallel operation. The converter's output current and its voltage will be controlled by nested loop control. This study proposes adaptive droop control parameters that are updated and verified online using the principal current sharing loops to minimize the fluctuation in load current sharing. When the converters in the microgrid are paralleled, load sharing will be accomplished using the droop control approach in addition to nested proportional-integral-based voltage and current control loops. To restore the correct voltage across the DC microgrid, an outer addition voltage secondary loop will be used, rectifying any voltage disparities caused by the droop management strategy. Several common load resistances and input voltage variations are used to test the suggested method. Using a linearized model, this work assesses the stability and performance of the proposed method. It then confirms the findings with an adequate model created in MATLAB/SIMULINK, Real-Time Simulation Fundamentals, and hardware-based experiments.
