“…Microgrid systems usually have a storage system to maintain the power balance in the system, and there are various types of storage, such as hydrogen [31][32][33], batteries [34][35][36][37], supercapacitors [38], electrochemical [39,40], and other types of storage [41]. The main purpose of any storage type in a microgrid system is to accumulate excess power when demand is lower than supply and use it at times when demand is greater than supply.…”

Microgrid systems may employ various combinations of system designs to connect generating units, and the number of different system designs increases exponentially upon adding different brands of inverters to a system. Each of the different microgrid system designs must be set up in a way that it works in balance. An example of an unbalanced microgrid system is given in this paper, with the main issue being the non-predictive excess power, which causes a frequency rise and faulty conditions in the microgrid system. There are many simple options for controlling excess power in a microgrid system; however, none of these options solve the issue permanently while ensuring excess power control without affecting the system’s accumulated energy—the battery state-of-charge (SOC) level. Therefore, there is a need to create a variable average power load (VAPL) device to utilize the excess power at a rate it is changing to avoid a reduction in accumulated energy. The main goal of this study is to review average power control methods for the VAPL device and provide guidance to researchers in selecting the most suitable method for controlling excess power. A key finding of the paper is a suggested optimal average power control method ensuring that the VAPL device is versatile to implement, economically attractive, and not harmful to other devices in a microgrid system.

“…The cover factor is an indicator of load-shifting technology and is meant to handle volatile primary energy carriers such as wind and sunlight, by deploying intermediate storage devices [21][22][23][24][25][26]. In addition to shifting, Eltanay et al [23] prioritized loads by dividing them into two major groups.…”

Modern households usually have independent energy sources such as wind generators, photovoltaic (PV) panels, and similar green energy production equipment. Experts predict that soon, there will be an increasing number of such prosumers who both produce and consume energy. This process alleviates and reduces the load on large national electricity networks and also contributes to overall energy security. In this paper, a simulation model of a household, which employs a wind generator as its independent source of electricity, is developed. It is expected that this approach will be easily replicated for more complex configurations. The other components of the single prosumer microgrid that will be assessed are the non-shiftable electricity consumption equipment, which is used mainly in households and deployed separately for water heater, with a separate battery to meet the needs of these non-shiftable consumers. The 5-min data intervals for the year of simulation have been used. The characteristics of energy flow according to production and consumption schedules and the capacity of storage equipment have been modelled and simulated. Results disclose that wind turbine production size and buffer battery have a crucial impact on the demand cover factor.

“…SolidWorks is used for the 3D model design [1,4] and MATLAB/Simulink [11][12][13] (specifically, the Simscape/SimMechanics library) is used for the physical model, thus providing its dynamic simulation [1,14]. The final simulation can partially replace the real (physics) prototype.…”

When designing a mechatronic system, several steps are taken into account. One of the main steps is the design of a CAD model representing the physical part of the system, and another major point is the development of the mathematical model necessary for the respective controller design. This paper combines both design steps and shows the advantages of using this approach. First, a CAD model is created considering the kinematic and dynamic behavior of the system as well as respective material properties. This CAD model is, in parallel, used for both purposes: as the main basis for developing a mathematical model that will be used for definition of control laws and appropriate system controllers, and also to generate a physical model as result of exporting to MATLAB/Simulink (Simscape/SimMechanics library) in order to simulate the system behavior. This translation does not consider only the standard CAD model export to the SimMechanics library when forces and torques between links are clearly defined, but also the correct way to add corresponding limiting forces/torques. When comparing the behavior of the physical model and the mathematical model, it is important to obtain similar results, especially when it is necessary to perform some simplifications of a mathematical model, as happens in the context of nonlinear systems control. All these issues are discussed in this paper and the obtained simulation results for both models are similar, which confirms the proposed approach.
