“…Therefore security factors shall be fully considered at the stage of power system planning, and narrow the scale of accident, reduce the loss of social economy to the greatest extent. To those traditional power system which only contains synchronous generator and loads, the main theory to determine power system subareas are: graph theory [7], slow coherency [8][9] and intelligent optimization [10] [11]. However, in traditional power system there are few distribution generators, storages and other new power devices such as smart meter, PMU, those methods for subareas above cannot apply to complex power system to answer for cyber security.…”

Abstract. Relying on the National High Technology Research and Development Program, this paper introduced the key issues in Cyber Physical Distribution System (CPDS), mainly includes: composite modelling method and interaction mechanism, system planning method, security defence technology, distributed control theory. Then on this basis, the corresponding technical route is proposed, and a more detailed research framework along with main schemes to be adopted is also presented. IntroductionCyber physical system integrates computation, networks and physical environments into a multidimensional complex system via 3C (Computation, Communication, Control) technology, and enables large-scale project to realize real-time perceiving, dynamic controlling and information services [1]- [2]. As the level of the utilization of information enhances unceasingly, Modern distribution system has developed to be a multi-dimensional cyber physical distribution system (CPDS) which highly relies on information, and follows traditional power system process [1][3]- [4].Although the traditional distribution system which has a complete "produce-supply-users" ternary coupling mode, has been mature enough, with varies of distributional sources, storages, protections and sensors plugging in, acute problems such as distribution system topology, information interaction, cyber-physical integration come into sight.Compared to traditional distribution system, CPDS has distinguishing features:(1) Multi-source isomerism, complex network. The distributional loads and the intermittent renewable sources changed the feature that power flows in single direction, and the exponential growth in the sensors along with communication devices, also causedthe physical topology to grow enormous and complex, and its dynamic behavior becomes non-linear, uncertain, time-varying, and isomeric.(2) Frequent interaction, andhence vulnerable Since smart meters, distributional storages and sources plug in, to realize massive information collecting, transferring, controlling and demand side response, power flow and information flow interacts frequently, thus information security becomes a serious problem. While the communication protocol, which is open and standardized, also bring new hidden dangers to traditional power system field, such as dispatching automation, relay protection and safety equipment automation, load control,

Since last decades, the pulse width modulation (PWM) techniques have been an intensive research subject. Also, different kinds of methodologies have been presented on inverter switching losses, inverter output current/ voltage total harmonic distortion (THD), inverter maximum output of DC bus voltage. The Sinusoidal PWM is generally used to control the inverter output voltage and it helps to maintains drive performance. The recent years have seen digital modulation mechanisms based on theory of space vector i.e. Space vector PWM (SVPWM). The SVPWM mechanism offers the enhanced amplitude modulation indexes (MI) than sinusoidal PWM along with the reduction in the harmonics of inverter output voltage and reduced communication losses. Currently, the digital control mechanisms have got more attention than the analog counterparts, as the performance and reliability of microprocessors has increased. Most of the SVPWM mechanisms are performed by using the analog or digital circuits like microcontrollers and DSPs. From the recent study, analysis gives that use of Field Programmable Gate Arrays (FPGA) can offer more efficient and faster solutions. This paper discusses the numerous existing research aspects of FPGA realization for voltage source inverter (VSI) along with the future line of research.

In the inverters, PWM makes it conceivable to control both the frequency and magnitude of the current and voltage connected to a motor. Along these lines, PWM for motor drives offers better efficiency and higher performance contrasted with fixed frequency motor drives. PWM systems have been the subject of serious research amid the most recent couple of decades. The PWM techniques have been the intensive research subject. Also, different kinds of methodologies have been presented on inverter switching losses, inverter output current/ voltage THD, inverter maximum output voltage of DC bus voltage [1].The sinusoidal PWM is utilized to control the output current/voltage of the inverter and keeps up a better performance of the drive in the whole operational range between 0-78percent of the value that would be come to by square operation. In the event that the MIs surpass this value, straight relationship amongst MI and output voltage is not kept up, and the over modulation techniques are required. As of late, a characteristically advanced modulation system known as SVPWM which depends on space vector hypothesis [2]. It has been accounted for that SVPWM mechanisms offers better performance over different methods regarding torque ripple, better DC link utilization, lower THD, switching loss and easier digital system

The droop controller is widely used for the parallel operation of inverters. However, the conventional droop controller has a trade-off between the power sharing and the regulations of the output voltage amplitude and frequency. In order to remove this trade-off, a new droop controller is presented in this paper. This method adopts the structure of the robust droop controller and utilizes the transient droop characteristic, which enables proportional power sharing without output voltage amplitude or frequency deviation. Simulation results are provided to demonstrate the feasibility and excellent performance of the proposed controller.
