In this study, two schemes of solar electrical power generation are designed and compared according to solar collection area minimization. The one comprises the parabolic trough collector, dual-tank of molten salt heat storage, and Organic Rankine cycle. The other consists of photovoltaic cell, polymer electrolyte membrane water electrolyzer, and polymer electrolyte membrane fuel cell. The effects of irradiation value, environmental temperature, and energy storage type on thermodynamic performance were investigated. The results indicated that the solar irradiation value had a more obvious effect on the PV (photovoltaic) cell performance than environmental temperature, and the PTC (parabolic trough concentrator) performance was improved with the increases of solar irradiation value and environmental temperature. The environmental temperature effect was negligible; however, the influence of irradiation value was obvious. Irradiation value had a positive effect on the former system, whereas it demonstrated the opposite for the latter. The latter system had much lower efficiency than the former, due to the low conversion efficiency between hydrogen energy and electrical energy in the polymer electrolyte membrane water electrolyzer and fuel cell. Stated thus, the latter system is appropriate for the power generation system with non-energy storage, and the former system is promising in the power generation system with energy storage.

Microgrids are small scale electrical power systems that comprise distributed energy resources (DER), loads, and storage devices. The integration of DER into the electrical power system basically allows the clustering of small parts of the main grid into Microgrids. Due to the increasing amount of renewable energy, which is integrated into the main grid, high power fluctuations are expected to become common in the next years. This carries the risk of blackouts to be also more likely in the future. Microgrids hold the potential of increasing reliability of supply, since they are capable of providing a backup supply during a blackout of the main grid. This paper investigates the black-starting and islanding capabilities of a battery energy storage system (BESS) in order to provide a possible backup supply for a small part of the main grid. Based on field tests in a real Microgrid, the backup supply of a residential medium voltage grid is tested. Whereas local wind turbines within this grid section are integrated into this Microgrid during the field test, the supply of households is reproduced by artificial loads consisting of impedance- and motor loads, since a supply of real households carries a high risk of safety issues and open questions regarding legal responsibility. To operate other DER during the island operation of such a Microgrid, control mechanisms have to ensure the power capabilities and energy reserves of the BESS to be respected. Since the operation during a backup supply of such a Microgrid requires a simple implementation, this paper presents a simple master–slave control approach, which influences the power output of other DER based on frequency characteristics without the need for further communication. Besides the operation of other DER, the capability to handle load changes during island operation while ensuring acceptable power quality is crucial for such a Microgrid. With the help of artificial loads, significant load changes of the residential grid section are reproduced and their influence on power quality is investigated during the field tests. Besides these load changes, the implementation and behavior of the master–slave control approach presented in this paper is tested. To prepare these field tests, simulations in Matlab/Simulink are performed to select appropriate sizes for the artificial loads and to estimate the expected behavior during the field tests. The field tests prove that a backup supply of a grid section during a blackout of the main grid by a BESS is possible. By creating the possibility of operating other DER during this backup supply, based on the master–slave control approach presented in this paper, the maximum duration for this backup supply can be increased.
