With the rapid development of restructuring power industry in China, the foundation of East China and Northeast China Regional Power Markets is the first step to establish the Regional Electricity Market, which is considered to be suited to the situation of our country by most of us. But nobody can positively assure that it is one whole market, named Unified Market, or market including two sub-markets, named Delaminating Market, more benefit to the market participants. And so it is the question that the thesis is discussing.Based on the introduction of PJM's organization mode, the dispatch management modes, trade modes, congestion management modes and ancillary service modes in different organization modes are discussed carefully. And the advantages and disadvantages of two modes are proposed.The emphasis of this thesis is to discuss the calculation methods for the Locational Marginal Price (LMP) and Market Power (MP). Including the materials as follows: 1). A LMP calculation method based on Optimal Power Flow (OPF) in two different modes is analyzed particularly. And the means that a generation in Delaminating Market takes part in the market is discussed. Then the congestion management modes using LMP in two different markets are introduced via a simple example.2). The conception of Market Power and it's weighing index used usually are introduced, and according to the shortages of HHI Index and Lerner Index as the MP's judgment standard, a direction of improving HHI Index is proposed. Then a new MP judgment method based on OPF is brought forward in two situations considering line limit or not. The aim of judging MP is to control it, so the MP monitoring and control methods in two organization modes are introduced.At last, based on the data of IEEE 30 nodes test system and applying the methods discussed in former chapters, the models organized with Unified Market Mode and Delaminating Market Mode separately are proposed and the LMP, MP, line power flow, congestion situation and system total cost in two market models are calculated. After contrasting the two groups of results, Delaminating Market Mode consists of agility and can benefit the development of establishing the Regional Power Market.
