Abstract-Approval standard of electricity price is currently the focus of discussion in the national wind power industry. How to determine an appropriate electricity tariff to promote the sustainable and healthy development of wind power is the urgent problem that wind power company need to solve. In this paper, a generation cost assessment model for wind power is established, taking the cost accounting...
Based on full investigation and further research of DSM, this paper established comprehensive evaluation index system, adopting fuzzy mathematics and Grey Theory. It established evaluation matrix of ray fuzzy in grey statistics, defining the weight of evaluation index according to grey correlation analysis. Evaluating the effect of DSM according to maximum membership degree principle, furthermore,...
The operational efficiency of electric power industry must be evaluated under the reform oriented to market. Considering the characteristics of electricity market, the limitations of traditional efficiency evaluation approaches were pointed out. A new concept of coordinated territory that constituted by some key indices which reflect the conditions of the market was put forward. The way of how to...
This paper, basing the climate parameters of Nanjing, taked a south bay window of PVC casement hollow glass windows as the subject and calculated energy consumption of the bay window using MATLAB when the window had no external sunshade and different external sunshade ways were applicated. Then energy conservation character was analysed The results show that energy-saving effect of the whole bay window...
The negative effects of generating power through burning coal on China's ecology are expounded. On the basis of the discussion of the development and application of new type power sources, the paper analyzes the urgency and flexibility of optimizing the structure of the sources of electric power supply and puts forward some countermeasures to the problems.
The generation of electricity based in the renewable energy sources has becoming a more significant in the last years because of continues increase on energy demand and fossil oil energy dependence, additional to preoccupation of environmental. Wind and PV power systems to generate electricity in The Republic of Cape Verde are analyzed in this paper. The power electronics converters and electrical...
The constrained hydroelectric unit commitment problem is turned into an unconstrained optimization problem by means of penalty function method, and to improve the diversity and search ability, the classical particle swarm optimization (PSO) approach is enhanced by incorporating a genetic crossover operator and a self-adaptive decreasing inertia weight. Then the enhanced PSO is used to solve the hydroelectric...
Demand Response (DR) plays an important role in shifting peak load, reducing energy consumption and so on, while Demand Response involves multi-party interests (power companies, users, etc.), so economic benefits of Demand Response and its distribution is very important for all the parties. On the basis of optimal spot pricing with Primal-dual interior point algorithm, the distribution pricing model...
As a new power distribution logistics means the power industry, power industry has been operating as an important part of the activities. This paper analyzes China's current electricity distribution patterns and defects, then the supply chain model of China's electricity distribution further analysis, given the optimal power distribution planning model.
The reform of electricity price is the core of electricity deregulation, and reasonable price should be an organic unity of price level and price structure. The examination of the effects of peak-load price under different price cap forms dawns on us that the price cap regulation has the effects of cost-recovery. Comparing with absolute price cap regulation, the relative price cap regulation is more...
Normally, The air-source heat pump (ASHP) can not work well in the serious cold regions of china in winter. In order to study this issue, the experiment system of Air-source Heat Pump using exhaust of building as Heating Source was developed, the system used the surplus energy of exhaust fully, raised the air temperature of ASHP, recovered the energy of exhaust by direct exchange, and heated fresh...
In the market, the future competitive forces of power companies depend on their abilities of managing and using the risk. The electricity market of our country has formed new operation mode that the power grid is divided into three levels which are the national network, regional network and provincial network. Provincial power company will face the risk of higher electricity purchased costs and insufficient...
Taking the fuzzy and grey features of transformer substation construction project into account, this paper classified the evaluation system of transformer substation construction project into 4 indexes of grade A and 13 indexes of grade B. The weight of each index is decided reasonably by the Analytic Hierarchy Process (AHP).The grey number and the grey evaluating weight of each index are obtained...
We introduce a new plan repair method for problems cast as Mixed Integer Programs. In order to tackle the inherent complexity of these NP-hard problems, our approach relies on the use of Supervised Learning method for the offline construction of a predictor which takes the problem's parameters as input and infers values for the discrete optimization variables. This way, the online resolution time...
`Scenario-Response' has been regarded as a more effective emergency management model to unconventional emergency response. Started with the decision-making research for unconventional emergency, this paper analyzes the importance and relevance of scenario in the decision-making process for unconventional emergency. In accordance with this, the article demonstrates the whole decision-making process...
The growing environmental concerns and increasing electricity prices have led to wider implementation of demand-side activities and created a new class of consumers, called demand response resources (DRRs). The DRRs actively participate in the electricity markets as buyers of electricity and sellers of load curtailment services. The demand profile modifications resulting from the DRR curtailments...
Today's capacity markets may be viewed as an additional source of income for generators to compensate the money lost due to regulatory imposed caps. Those additional money flows and other design characteristics serve, theoretically, to achieve system adequacy in a market environment. In this paper, we analyze key aspects of today's capacity market designs. Our main finding is that some design elements...
Photovoltaic (PV) power generation is the most promising power generation. In this paper, we summarize the significance of PV power generation, two application types of PV power system, as well as the development of Chinese PV industry history, and point out some problems of the current PV industry in China.
A new design process of a phased array antenna at 2GHz is presented by the simulation method. First a suitable antenna pattern for the radiator of Vivaldi is selected as a slot antenna with light weight, small volume, low cost and high gain. A kind of the analysis software of high frequency structure simulation CST MWS is optimized for the VSWR and radiation pattern. However, several antennas with...
The paper introduces the electric energy data acquisition terminal based on the latest standard of Q/GDW373, which implements an intelligent energy acquisition system by exchanging information with the hub, collecting information from voltage current transformer and communicating with the electrical energy meter. The paper also recapitulates the function of the system, the components of hardware and...
