Abstract The decision‐making and risk assessment of electricity purchase sales is the key to adapt market for independent retailers in China. This research carried out risks constructed multi‐level combination optimization model. Based on portfolio theory, conditional value at theory (CVaR) was proposed. evaluation index about profit CVaR, combined model has been explore impact by different factors market. example analysis fixed spread mode linkage mode. results showed that mathematical mean...

In order to reduce thermal power generation cost and improve its market competitiveness, considering fuel quality, cost, creditworthiness, sustainable development capacity factors, this paper established the evaluation system for coal supplier selection of put forward strategies based on integrated empowering ideal matter-element extension models. On one hand, model can overcome limitations subjective objective methods determine weights, better balance subjective, information. other since...

As an efficient way to deal with the exhaustion of traditional fossil fuels, new energy power generation has obtained much attention from Chinese Government. In this context, more and groups that consist large numbers regional enterprises have been founded developed rapidly. However, researches related comprehensive benefit evaluation group-affiliated is still blank in China, which will hinder growth sustainable development such enterprises. A novel hybrid indicator system proposed both...

To optimize the use of distributed energy, this work builds a combined cooling heating and power system (CCHP) driven by including three subsystems: electricity subsystem, CCHP ground source heat pump (GSHP) subsystem. Then, economic environmental performance indicators are constructed using natural gas‐driven (NG CCHP) as frame reference. Thirdly, operation modes put forward, following thermal load (FTL) mode, electric (FEL) combine (ECT) mode. In meantime, kinds proposed, optimization...

The operating environment of power grid enterprises is complex with a range monitoring indicators. To grasp the overall operational status in time and find key affecting factors, Balanced Scorecard Card (BSC), Interpretive Structural Model (ISM), Principal component analysis (PCA) should be applied. This paper proposed several enterprise operators indicator systems (which include achievement indicators driver indicators), applied PCA for verification evaluation. mainly reflected...

In order to promote grid’s wind power absorptive capacity and overcome the adverse impacts of on stable operation system, this paper establishes benefit contrastive analysis models plug-in hybrid electric vehicles (PHEVs) under optimization goal minimum coal consumption pollutant emission considering multigrid connected modes. Then, a two-step adaptive solving algorithm is put forward get optimal system scheme with highest membership degree based improved<mml:math...

A half-rate clock and data recovery (CDR) circuit for 60GHz communication with 20Gbps QPSK modulation in 65nm CMOS is presented. hybrid DC-offset cancellation loop (DCOC) proposed to calibrate the input offset. duty cycle distortion (DCD) cleaning up adopted minimize negative impact on half rate sampling CML-CMOS conversion, a quadrature calibration (QCC) utilized correct I/Q phase mismatch. The CDR based interpolator (PI) uses clocks from divider of main PLL. whole consumes less than 16mW...

Carbon emissions of power industry in China have accounted for more than half the total emissions. How to decrease them is important realizing carbon emission reduction. This paper proposes a market feedback mechanism market, comprehensively considering influence generation structure, intension, and technological progress on reduction industry, builds potential model based dynamic system. Operation system results show that increasing trend can be controlled effectively but always with lag....

For the technical and allocative efficiency evaluation of smart grid, this paper has proposed two methods. One is based on Data Envelopment Analysis another Stochastic Frontier Model. Among them, former considered dynamics grid development influence parameter. The latter analyzed self-duality between Cobb-Douglas production function cost function; then, it deduced resources optimization model which can avoid price information needs input factor in conventional evaluation. validity...

With the proposal of national "carbon peaking and carbon neutrality" "building a new power system with energy as main body" other goals, cleaning digitization have become an urgent need for systems. Based on advanced control, metering, communication technologies, virtual plant aggregates massive multi-distributed resources demand side, which can provide necessary flexibility support through diversified means saving, at same time help renewable consumption. The digital twin technology uses...

Based on the total life cycle theory, this paper constructs a carbon cost accounting model for equipment and transmission distribution pricing that takes into account sharing, based this, by combining theoretical methods various types of users at different voltage levels, drawing spread method to measure proportion scale cross-subsidies shared industrial commercial residential agricultural users, it finally puts forward price cost.

In the era of growing emphasis on dual-carbon policies, accounting for carbon emissions cost in transmission and distribution tariffs power grid enterprises should become crucial enterprises, which is main source emissions. This paper incorporates costs
