Abstract—In this article, a complete methodology to design the primary voltage droop control for a generic DC microgrid is proposed. . Primary droop control allows GFM inverters to share power without communication; however, it is necessary to dispatch GFM inverters and/or SGs with the desired output power for better energy management (e., one GFM inverter needs to charge the battery due to a low state of charge). Therefore. . For this purpose, a power based droop control solution is pro-posed to control the DC voltage fast, as well as to establish power sharing between converters connected to the DC grid. While widely utilised, Conventional Droop Control (CDC) techniques often. . Microgrid control can be classified as centralized and decentralized. Then, this linear model is. .

In this work, HESS charging and discharging control strategies were developed based on adaptive droop control, which regulates the power distribution between the SC and the battery and limits DC grid voltage deviations. A typical application of such systems is solar-powered water pumping. However, since solar irradiance varies throughout the day, the. . The control strategy of a distributed photovoltaic (PV) power generation system within a microgrid consists of an inner-loop controller and an outer-loop controller. The inner-loop controller is divided into two types, namely, the maximum power point tracking (MPPT) control strategy and DC bus. . The traditional battery SOC control strategy often uses a fixed droop coefficient, but this method has problems such as large DC bus voltage deviation and slow SOC equalization speed, which limit the performance of optical storage DC microgrid.
