The interconnected European transmission system for electricity supports the electricity trading across Europe, promoting the maximization of welfare, in particular when the interconnection capacity is enough to take low marginal cost generation, namely variable renewable power generation, into the demand areas where it is scarce. Transmission systems operators (TSOs) calculate the available interconnection capacity for the day-ahead and intraday markets in a coordinated way. This is a key step to enable price-based market coupling between different countries and regions and, therefore, efficient use of electricity from renewable energy sources and effective distribution of the benefits of renewable electricity across Europe. This work addresses the calculation of interconnection capacity between bidding zones by analyzing the processes and comparing the different methodologies used by European TSOs to coordinate the capacity calculation and compute the underlying generation shift keys (GSKs). The paper focus on the Portuguese cross-border transmission capacity with Spain, where the merit order methodology defines the GSKs supporting the calculation of the Available Transmission Capacity (ATC) for the spot market.

power dispatching is an important link in the direct production, transmission and distribution of electric energy, and is one of the core components of the power system. It has the characteristics of many types of equipment, complex data structure attributes, and high data acquisition density. At present, the operation data of power grid dispatching and control has been gradually collected in the cloud, and the data assets have begun to take shape. However, the management and operation mode of these data is rough, and they are still used and managed by various business departments. As an intangible asset, the value of data has not been paid enough attention and deeply excavated. From inside and outside the industry, the concept of data as an asset has become a consensus, but in the field of power, the management and application of data assets is still in the exploratory stage. At the same time, in the construction of data capitalization, many methods of other industries are difficult to be directly applied in the field of dispatching and control, so it is urgent to integrate the characteristics of power grid dispatching and control business needs and propose a data capitalization mode with business characteristics. This paper gradually focuses on the scope of power data assets from the broad sense of data assets, and regulates the big data capitalization management. The planning method of dispatching data assets analyzes and summarizes the construction of dispatching data assets, and provides data asset management support for subsequent big data applications and data mining.

The unit commitment (UC) problem has been extensively researched in the literature, which is typically formulated as a mixed integer programming (MIP) problem. However, current studies lack effective methods to identify potential UC problem structures within a general MIP problem, making it challenging to leverage well-established valid inequalities for UC problems to accelerate the solution process. In this paper, we present a novel detection method that automatically identifies UC structures within an MIP problem by analyzing the relationships between variables and constraints. Moreover, we enhance the MIP formulation by incorporating three well-studied classes of valid inequalities as cutting planes, based on the identified UC structures. Our experiments demonstrate that our proposed UC detection method greatly improves computational efficacy of a standard MIP solver compared to the default setting.

With the rapid and profound changes in all aspects of power system, the control scale increases exponentially, the characteristics of control objects vary greatly, the bilateral uncertainty of source load increases, and the power grid real-time dispatching will be more complex and frequent. In this paper, we combine current advanced artificial intelligence technology and power grid dispatching business needs, design and develop power grid operation environment simulation system based on reinforcement learning. The system determines the power grid scenario according to the user's choice, applies the real-time power grid operation data, directly interacts with the decision agent, realizes the agent's autonomous learning and continuously improves its regulation and decision-making ability. The system has good feasibility, practicability and scalability, realizes the standardization of workflow, and provides an effective decision support tool for power grid dispatching.

China's administration proposes to carry out reform by taking a province as a unit and gradually establish a market-oriented inter-provincial electricity trading mechanism. Since then, eight provincial spot market pilots have entered the phase of settlement trial operation, and electricity market reform has been widely carried out. On this basis, how to further build the inter-provincial electricity spot market and coordinate with the provincial markets is an important issue in the construction of electricity spot markets in China. Based on mainstream market models abroad, this paper analyzes the trans-regional trading models in Europe and the United States and their inspiration to China. Then it introduces the current situation of construction of a trans-regional electricity spot market in China and analyzes its existing problems. Based on this, combined with the actual situation of dispatching management and operation in China, it is pointed out that the spot market in China shall adopt the market model of “unified market and two-level operation” and adopt the market process of “inter-provincial before intra-provincial The benefits produced by this model are analyzed. The main market framework is designed from three aspects of market participants, trading timing and optimization process. Finally, the key technical requirements for building the inter-provincial electricity spot market in China are abstracted.

The power flow may get redistributed once fault occurs and transmission line get broken. This paper proposed a power grid line breaking identification method based on parallel power flow Figure using deep learning. The method is based on the convolutional neural network (DN). Firstly, the principle and technical idea of using parallel power flow Figure (PFF) to identify line disconnection are introduced. After that, based on the static PFF concept proposed by the author in the early stage, the trend characteristics of the power flow are added, the concept of PFF is proposed, and the method of generating massive PFF sample sets is given. Finally, a DN that conforms to the PFF dimension is designed, and the method can accurately identify the line disconnection. The example shows that the designed DN structure can extract the spatiotemporal features in parallel PFF samples. Compared with the static PFF method, the accuracy of using the parallel PFF for grid line breaking is significantly improved. © 2020 IEEE.
