Problems of the current electricity transaction include high maintenance costs, low efficiency, and insufficient security. A possible solution should be proposed tentatively with a blockchain-based model for distributed electricity. This paper attempts to build decentralized trading scenario within by introducing blockchain technology, combining reliability coefficient both smart contract credit value mechanism. Finally, are introduced into simulated transaction. The results show that...

China's wind power is primarily distributed in West China which far away from the load center. Power these farms difficult to consume, so it needs be transmitted East extend its consumption area. To coordinate interregional construction and make full use of generation resources, especially electricity, a joint plan for an source grid necessary. A mixed integer programming model electric investment dynamic optimization established many reasons. The most important reasons are optimal operating...

Safety evaluation is a complex problem that often faced by decision makers in the power supply enterprises. It has significant impact on safety of industry. enterprises multiple criteria making (MCDM) problem. The model constructed according to China State Grid's regulation. A hybrid elimination et choice translating reality (ELECTRE) III and technique for order performance similarity ideal solution (TOPSIS) been specially developed evaluate level experience application methodology presented.

The global electricity supply from non-hydro renewable energies, such as wind and solar, has being growing at a high rate, it is expected that this trend persists. In China, Wind power one of the most mature energy technologies possible to be utilized in large-scale. However, long run, malicious competition will break rule monopoly market under control utilities China prevent development Chinese power. Reasonable investment key promote healthy industries China. Based on game theory, paper...

Residential load is one of the important components seasonal peak power grid, and it increasing each year, with a huge demand response potential. With development energy digital economy, new system shows characteristics multi-stakeholder participation. The mode based on value co-creation has become prominent support for market-oriented reform, need promotion smart electricity use increasingly prominent. In order to realize in-depth exploration residents’ potential sustainable “value...

In order to promote the achievement of "double carbon" target, a log-average weighting decomposition method was used analyze factors influencing carbon emissions in power sector, which accounts for highest China. The main namely share energy, coal consumption generation, ratio thermal generation total electricity and consumption, were analyzed by modified Kaya constant equation Divisia method, positive driving effect on sector found be strongest. negative proportion is obvious, energy very weak.

In order to forecast power futures price exactly, a radial basis function neural network (RBF NN) method is used in this paper. The RBF NN has the advantages of rapid training, generality and simplicity over feed-forward network. data Nordic electricity market adopted for case analysis. Empirical results reveal that more accurate result than back-propagation (BP method. can effectively price.

Using the time serial data of Shanghai from 1978-2010, this paper studies long-term equilibrium relationship, shortterm dynamic relationship and Granger causality among Shanghai's urbanization, economic growth energy consumption.The results indicate that consumption are co-integrated in long-run urbanization cause development, reason running to development short-run there is bi-directional between consumption.

This paper proposes a new collaborative design method, which is developed from the study of dependencies between parameters each part apparatus, and can be devoted to solve problems product multiple domains several communities based on computer networks, applied process such as electrical application mechanical etc. covers emerging issues persistent requirement in industry, then elaborates foundation ideas formal definition systems dependency, corresponding architecture.

Renewable generating technologies offer an effective means for climate change mitigation and guaranteeing energy security. As we all known that, the widespread perception that these renewable have more risk than conventional alternatives. So, it is investment-decision problem. Investors commonly evaluate such problems using portfolio theory to manage maximize performance under a variety of unpredictable economic outcomes. Absolute deviation utilized as measure new function provided market...
