Smart gird, integrated power network with communication network, has brought an innovation of traditional power for future green energy. Optical fiber technology and synchronous digital hierarchy (SDH) technology is widely used in smart grid communication transmission network. It is a challenge to reduce impact of the availability of smart grid communication services caused by random failures and random time to repair. Firstly, we create a service channel violation risk degree (SCVRD) model to precisely track the violation risk change of communication service channel. It is denoted by the probability of service channel cumulative failure duration exceeding the prescribed duration. Secondly, a service channel violation risk degree routing mechanism is proposed to improve the availability of communication service. At last, the simulation is implemented with MATLAB and network data in one province are used as data instance. The simulation results show that the average service channel failure rate of availability-aware routing based on statistics (AAR-OS) algorithm and risk-aware provisioning algorithm are reduced by 15% and 6%, respectively.

“…With the development of science and technology as well as the continuous growth of energy demand and power grid, China has entered into an era of super intelligent interconnected electric network with ultra-high voltage and long distance transmission [25][26][27][28]. However, with the constraints of regional different resources endowment and power grid characteristics, the dependence of receiving-end grid on external electricity under the condition of long distance transmission is constantly strengthening [29,30]. So, people increasingly pay attentions to the security and stability of interconnected power grid operation [31].…”

There are still residents without access to electricity in some remote and less developed areas of China, which lead to low living standards and hinder sustainable development for these residents. In order to achieve the strategic targets of solving China's energy poverty, realizing basic energy service equalization, and comprehensively building up a moderately prosperous society, several policies have been successively promulgated in recent years, which aim to solve the electricity access issue for residents living in remote and less developed areas. It is of great importance to determine the most economical mode of power supply in remote and less developed areas, which directly affects the economic efficiency of public investment projects. Therefore, this paper focuses on how to select the most economical power supply mode for rural electrification in China. Firstly, the primary modes to supply electricity for residents living in the remote and less developed areas are discussed, which include power grid extension mode and micro-grid mode. Secondly, based on the levelized cost of electricity (LCOE) technique, the life cycle economic cost accounting model for different power supply modes are built. Finally, taking a minority nationality village in Yunnan province as an example, the empirical analysis is performed, and the LCOEs of various possible modes for rural electrification are accounted. The results show that the photovoltaic (PV)-based independent micro-grid system is the most economical due to the minimum LCOE, namely 0.658 RMB/kWh. However, other power supply modes have much higher LCOEs. The LCOEs of power grid extension model, wind-based independent micro-grid system and biomass-based independent micro-grid system are 1.078 RMB/kWh, 0.704 RMB/kWh and 0.885 RMB/kWh, respectively. The proposed approach is effective and practical, which can provide reference for rural electrification in China.Sustainability 2017, 9, 910 2 of 18 and services with no discriminations regarding price, quality, and regions for any residents [5][6][7]. The electric universal service level not only reflects the guarantee for the rights of Chinese survival and development, but also is regarded as an important symbol of realizing basic energy service equalization and comprehensively building up a moderately prosperous society. In recent years, a number of policies have been promulgated in succession to promote the electric universal service for providing electric energy to residents living in remote and less developed areas, such as 'China's Energy Policy (2012)' promulgated by the State Council of China [8], 'Three-year action plan for comprehensively solving electric usage problems for rural residents (2013)(2014)(2015)' issued by the National Energy Administration [9], and 'Implementation opinions of speeding up energy development in poor areas to promote poverty alleviation (2016)' proclaimed by the National Energy Administration [10]. The relevant policies point out that the power grid extension and new energy-based micro-gr...

Traditional isolated modeling and calculation methods for cyber systems and power systems cannot satisfy the requirements for the analysis and control of cyber physical power systems (CPPSs). In this paper, a matrix-based modeling method for the coupled behavior of a CPPS is presented to describe the complex interactions of the information and energy flows. On that basis, a hybrid calculation architecture, which offers on-demand response and consists of multiple layers, is proposed for the reliability and security analysis of CPPSs. Case studies verify the effectiveness of this CPPS modeling approach and hybrid calculation architecture.
