“…Where the numbers of capacitors in row and column of the tray are equal to n, as figure 1 [5]. Hence, both row and column are having same number of capacitors, then according to the classical mathematics, the total number of capacitors can be written as [6]- [7], = = Hence the net capacitance is unit. Row and column both are designed with n numbers of capacitors, figure 1 [8].…”

This paper focusses on the physical characteristics of the Super Battery like energy, power and durability. Super Battery is such a kind of device which have an ability to charge itself within a short time period while external power source is present. The main motivation of this paper about this device, is to establish a high energy condensation inside the device. This paper is presented along with all the theoretical calculations for clarification of the device characteristics. Here, to achieve a high durability of the battery a concept of capacitor tray is introduced. With a less charging time it would be able to survive a long discharging efficiency. Keeping all trays are in parallel connection the achievement of the device power and durability is also demonstrated briefly inside. This paper summarizes a new technical information about super battery to the modern electronics industries.

“…STATCOM uses a three-level converter with two splitting DC capacitor is more applicable in high power application with less ripple and harmonic compared to a two-level converter which uses one DC capacitor [42]. In [43][44][45][46][47] SC coupled to STATCOM at DC-link capacitor is used to compensate active and reactive power, where STATCOM uses two-level converter. This paper proposes combination control for constant both active and reactive output power of wind farm (WF) during gust where STATCOM and SC are connected separately to wind energy system as STATCOM with a three-level converter is connected to the network and SC is coupled to each DFIG through DC-link capacitor.…”

This paper proposes constant active and reactive power control of a wind farm during gust using the supercapacitor (SC) and static synchronous compensator (STATCOM). The proposed technique is applied to Gabal El-Zayt wind farm which located in Red Sea region of Egypt with a capacity of 200 MW and equipped with doubly fed induction generators (DFIGs) and analyzed during gust wind. As the nature of wind is varying all time, the output power is changing continuously so energy storage system such as SC is required. SC is responsible for maintaining constant output active power by charging when there is excess in the output power of DFIG and discharging when there is a lack in the output power of DFIG. Reactive power compensation is achieved by connecting STATCOM to the power system. SC keeps reactive power constant however its value is improved by connecting STATCOM. Wind farm model is analyzed during gust with the proposed technique while active and reactive power performance is investigated. Firstly, the effect of connecting SC to each wind turbine is studied. Then the effect of connecting STATCOM to the electric power system is studied. Also, the effect of connecting SCs and STATCOM is studied. Finally, the impact of connecting additional STATCOM at different locations is investigated. Results show the proposed technique validity.

Abstract. With more penetration of solar power plants, photovoltaic generation will be exerting more influences on the power system. The main purpose of this paper is to study the dynamic characteristics of the power system with photovoltaic generation. First, power flow and bus voltage variations of the system with photovoltaic generation are calculated. Then according to the related interconnection criteria, the voltage variation and cable loading are inspected to determine whether the system complies with relevant specifications. Finally, the dynamic responses of the system are analyzed. This paper focuses on a sample power system with photovoltaic generation. The system dynamic characteristics are examined when three-phase faults occur, and the system voltage variations subject to illumination change are investigated. Results show that photovoltaic generation has less impact on system because the capacity of the photovoltaic generation is not high. The illumination change does affect both voltage and frequency of the system, and the system will return to a normal operating state after a period of time.
