in order to improve the reliability of the power system, sufficient amount of new capacity should be installed in the network. usually generation units’ payoff in an energy market is not adequate to cover their expenses. therefore, energy only market cannot induce investors to invest in generation field. due to energy only market inefficiency, a supplementary algorithm is suggested to cover the...

Market power assessment is a prime concern when designing a deregulated electricity market. In this paper, we propose a new functional market power measure, termed transmission constrained network flow TCNF , that takes into account an AC model of the network. The measure unifies three large classes of long-term transmission constrained market power indices in the literature: residual supply ba...

It is difficult to eliminate all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery, facilitate investment, and increase security of supply. This suggestion implicitly assumes all generation technologies benefit equally from market power. We assess a mixture of conventional and...

The consequences of the liberalisation electricity markets have been widely discussed in literature emphasising successes or failures privatisation and deregulation. While most developed power systems undergone a form economic transformation, they still require to be monitored analysed assess market power. Polish system is an example wherein potential examined fifteen years ago was summarised a...

the impact of price changes (at a level of market) on the other market levels (transfer of prices) will affect welfare of producers, marketing agents as well as consumers. in this study, asymmetric tea market is investigated through an application of johansen co-integration analysis and error correction model (ecm model) to time series of 1976-2009. co integration method used in the import mark...

introduction: market power is an important factor affecting welfare. existence of market power on the purchase side reduces supplier welfare. however, existence of market power on the sales side reduces supplier welfare. some believe that the agricultural market structure is a monopoly. in fact, most of the agricultural products can be purchased by small firms and then delivered to consumers be...

Abstract China is currently in the process of power market reform. With continuous deepening reform, there will be more and uncertain factors future market. Although advancement marketization bring benefits to players, it also Bringing huge risks. Thus, a monitoring indicator system great significance achieve risk management. The needs fully consider particularity commodities. In design process...

since the emergence of power market, the target of power generating utilities has mainly switched from cost minimization to revenue maximization. they dispatch their power energy generation units in the uncertain environment of power market. as a result, multi-stage stochastic programming has been applied widely by many power generating agents as a suitable tool for dealing with self-scheduling...
