Power generation maximization of distributed photovoltaic systems using dynamic topology reconfiguration

The ‘mismatch losses’ problem is commonly encountered in distributed photovoltaic (PV) power generation systems. It can directly reduce power generation. Hence, PV array reconfiguration techniques have become highly popular to minimize the mismatch losses. In this paper, a dynamical array reconfiguration method for Total-Cross-Ties (TCT) and Series–Parallel (SP) interconnected PV arrays is proposed. The method aims to improve the maximum power output generation of a distributed PV array in different mismatch conditions through a set of inverters and a switching matrix that is controlled by a dynamic and scalable reconfiguration optimization algorithm. The structures of the switching matrix for both TCT-based and SP-based PV arrays are designed to enable flexible alteration of the electrical connections between PV strings and inverters. Also, the proposed reconfiguration solution is scalable, because the size of the switching matrix deployed in the proposed solution is only determined by the numbers of the PV strings and the inverters, and is not related to the number of PV modules in a string. The performance of the proposed method is assessed for PV arrays with both TCT and SP interconnections in different mismatch conditions, including different partial shading and random PV module failure. The average optimization time for TCT and SP interconnected PV arrays is 0.02 and 3 s, respectively. The effectiveness of the proposed dynamical reconfiguration is confirmed, with the average maximum power generation improved by 8.56% for the TCT-based PV array and 6.43% for the SP-based PV array compared to a fixed topology scheme.     

Secure DACS Scheme

When customers with different membership and position use computers as in the university network systems, it often takes much time and efforts for them to cope with the change of the system management. This is because the requirements for the respective computer usage are different in the network and security policies. In this paper, a new destination addressing control system scheme (DACS Scheme) for the university network services is shown. The DACS Scheme performs the network services efficiently through the communication management of a client. As the characteristic of DACS Scheme, only the setup modification is required by a system administrator, when the configuration change is needed in the network server. Then, the setup modification is unnecessary by a customer, which shows a merit for both a system administrator and a customer. However, there is a problem to be solved. In existing DACS Scheme, it is assumed that DACS Client for controlling the communication must be implemented on all clients. If the client without DACS Client is connected to the network, each network server can be accessed from the client. Therefore, in this paper, secure DACS Scheme with the function to prevent the communication from the client without DACS Client is proposed and examined.     

基于SSH2的C2C系统安全策略

随着互联网的不断发展,以J2EE（Java 2 Platform Enterprise Edition）为代表的网络开发技术占据了Windows,Linux,Unix平台下大部分的市场份额.Java以平台无关性和安全性著称,然而面对不断更新的Web技术和不断升级的网络环境,安全问题仍然是J2EE开发不容忽视的问题.SSH2（Struts2 Spring Hibernate）作为Java WEB主流框架的整合,其安全控制策略至关重要.结合三农电子商城开发经验,从B/S（Browser/Server）3层体系结构出发,分层讨论C2C（Customer to Customer）系统的安全保证策略.
