In the past 20 years, China's economy has grown rapidly, but so has the country's power industry. This paper provides a comprehensive introduction on the current status and the future development of the power transmission systems and grids, which include HVAC and HVDC transmissions, regional...

The statistical tools of Complex Network Analysis are of useful to understand salient properties of complex systems, may these be natural or pertaining human engineered infrastructures. One of these that is receiving growing attention for its societal relevance is that of electricity...

Many scholars have applied complex network based models to investigate power grid vulnerability, but how effective are these models to capture the real performance is an interesting topic. This paper selects two typical complex network based models, including a purely topological model (PTM) and...

Several changes to the world’s electrical power systems and grids threaten to require massive infrastructure investment and cost to power utilities, especially increasing population and electrical energy demands, especially peak summertime air conditioning demands, and mismatches between...

Power system and its communication system, which can be called a cyber-physical system, are interconnected and interdependent on each other. This paper considers the interaction problem between power system and its communication module from the perspective of the topological structure. Firstly,...

We analyze a 19-year time series of North American electric power transmission system blackouts. Contrary to previously reported results we find a fatter than exponential decay in the distribution of inter- occurrence times and evidence of seasonal dependence in the number of events. Our...

We extend the WITCH model to consider the possibility to produce and trade electricity generated by large scale concentrated solar power plants in highly productive areas that are connected to the demand centres through High Voltage Direct Current (HVDC) cables. We find that it becomes optimal...

Large-scale blackouts are an intrinsic drawback of electric power transmission grids. Here we analyze the structural vulnerability of the Italian GRTN power grid by using a model for cascading failures recently proposed in Crucitti et al. (Phys. Rev. E 69 (2004)).

Many of the scenarios for decarbonising the European energy system involve the integration of large-scale and decentralised renewable energy sources, such as wind and solar power. However, such integration requires substantial and rapid improvements to the existing transmission grids. Using a...
