This paper researches on renewable energy proportion in the integrated energy, and proposes the development of renewable energy driving force to achieve the share target first. To the driving force, logic integration for industry chain and number integration for production and marketing have been done. Thus, the framework of renewable energy development can be reached. Based on this, the author puts...
Fostering the growth of energy management companies (EMC) has proven to be an effective market-based solution for improving energy efficiency in the Chinese economy. However, lack of financing remains the most significant barrier to the full development of small and medium sized EMCs. Thus, developing a new financing mechanism with local banks for energy efficiency projects is an essential strategy...
With the proposed of smart grid, the user's role in power system is being re-recognized. In order to realize user's role, many countries are implementing smart metering and demand response (DR). The investment of this system is so huge and the benefits of all parties participating in DR are not clear, all parties are not active to participate in it. In this paper, the problems of nonDR are listed...
Solid power system planning is fundamental to the safety, reliability and economy of power system operation. In the deregulated power grid environments, power grid planners not only have to handle massive geographic data, power equipment parameter data and grid operational data, but also have to solve very complex decision-making problems when they are committing power grid planning. Thus, it is necessary...
In the sealed-auction-based electricity markets, to fast and accurately solve the random-fuzzy programming problem, which is for building optimal bidding strategies of generation companies and can simultaneously deal with both random variable and fuzzy variable, a improved genetic algorithm (IGA) is proposed based on a genetic algorithm with hybrid Laplace crossover and power mutation (HLCPM). The...
In the current power market environment of China, lease operation mode of pumped storage power station is an efficient way to realize static and dynamic benefits of power station, also it's one of main operation mode in China. A two-party profit model among pumped-storage power station and grid companies was build. The profits of power station and grid company were discussed to meet the individual...
To regard environmental protection renewable energy sources especially wind, has been applied to achieve emission reduction goals. While wind generation does not directly produce air pollutants emission, it causes some changes on thermal power generation scheduling which may lead them to produce more air pollutants emission especially during low and medium energy demand periods. So it seems necessary...
The idea of smart grid is currently receiving much attention. However, there are differences in understanding of concept of smart grid and in how this concept should be implemented. Moreover, there is no clear agreement, worldwide, on what a power grid must include in order to be considered as smart grid. The fact is that with a growing demand for reliable and sustainable power supply, there is a...
To reflect the bilateral transaction's uncertain impact on the grid, the effective reserve and the reserve channel margin are defined. And reserve capacity is modeled based on stochastic simulation and bi-level programming considering the congestion risk, which the reserve services are regarded as object of study in the open power market environment. The upper optimization level is to maximize the...
Time-of-Use (TOU) pricing is one of Demand Response mechanisms that consumers shift load along with electricity price changes. A model of TOU pricing for a retail electricity market on Pareto Improvement method is proposed, based on the short-term marginal cost, considering the effect of consumer response by price elasticity matrix of electricity demand. The objective is minimum network losses while...
In the deregulated power systems, the interruptible load management (ILM) is widely used as an effective measure to ensure reliability and mitigate the market price spike. A critical issue is the incentive paid to the consumers to participate in the ILM. This paper addresses the quantification and allocation of ILM's benefit from mitigating the wholesale price spike. This benefit is calculated within...
In the smart grid environment, appropriate power energy exchange strategies will be necessary for energy intensive industries (EIIs) with industrial power plants. This paper presents a systematic approach that can cope with the integration of industry consumers and an energy exchange strategy aiming at achieving balance between power production and consumption in EIIs. A basic balance model using...
Along with the rising energy consumption in the world, new technologies will influence the way we generate, distribute and consume energy. Alongside others, distributed energy generation becomes a major trend in many countries. The fast upward penetration of Distributed Energy Resources (DER) and the ongoing trend towards a more competitive electricity market requires new technologies and policies...
High wind power penetration in power systems will significantly increase risks faced by the conventional generators in the deregulated electricity markets. This will further affect these generators' risk preferences and strategic behaviors. A supply function equilibrium model of electricity markets with wind power is developed taking into account the conventional strategic generators' risk preferences...
This paper proposes a new and practical model to achieve the electricity market equilibrium based on Linear Supply Function Equilibrium (LSFE) model. In the proposed model, the transmission constraint in addition to the generation constraint and the consumers bidding behavior are considered. The coevolutionary computational approach is proposed to solve the market equilibrium problem. Several cases...
This research aims to shed light on the difference among three collection strategies for agricultural biomass, i.e. commitment strategy, pure competition strategy and vertical integration strategy. Firstly, the assumptions of biomass distribution, cost structure and market structure are applied to describe the agricultural biomass market, this lead to lead to a monotonous increasing inverse demand...
Analyzing from the several main kinds of bidding mechanism for electricity market,the most important factor to judge the superiority and inferiority of bidding mechanism is the degree of information disturbance. From the perspective of signal transmission in game theory, this paper proposed a random matching mechanism of optimal probability to improve the fault of PAB Bidding mechanism. This mechanism...
On context of time-of-use electricity price market, this paper mainly proposes a feasible PHEV charging mechanism for peak load management, the grid's peak load regulation model and PHEV terminal cost model are separately established. In accordance with the mechanism, this paper also puts forward an optimization algorithm based on dynamic estimate interpolation concept. At last, an example is simulated...
The common maintenance scheduling problem in restructured power systems is addressed. When Independent System Operator(ISO) receives scheduling plans from multiple independent GENeration COmpanys (GENCOs), which seek to maximize their own medium-term profits, it tries to trade off the generation cost and the reliability of the system, thus reschedules the maintenance plans of the GENCOs. This paper...
Many challenging and new issues arise in China's power market process. In this paper the general and specific characteristics of power market research are analyzed and an integrated simulation system (IPMSS) based on experimental economics (EE) and agent-based computational economics (ACE) is designed. Further works include proposing a hybrid experimental method of experimenter and agent, and carrying...
