[0005] The inventors of the present invention discovered during the research process that the application of energy storage equipment in the scenario where a high proportion of distributed photovoltaic power generation systems are connected to the distribution network can reduce the transformation of the distribution network and photovoltaic curtailment, and reduce the cost of distributed photovoltaic power generation. The utilization cost of the system has certain value; however, the energy storage device is only one of the optional technical measures to improve the ability of the distribution network to accept the distributed photovoltaic power generation system, and the energy storage device cannot be used as the only technical measure in actual research. Usually, there may be power grid line transformation measures or technical measures for power reduction; and after research, the cost of using energy storage equipment measures alone may be higher than the cost of power grid line transformation technical measures or power limit technical measures.

The invention provides an energy storage application value evaluation method and system based on data processing. The method includes determining the access point of the energy storage device in a power distribution network under the condition that a distributed photovoltaic power generation system is connected to the power distribution network; determining the reconstructed lines in the power distribution network; determining technical measure combinations being divided into a technical measure combination using the energy storage device and a technical measure combination being free of the energy storage device at least based on the technical measures of power grid line reconstruction, power cutting, and energy storage device investment; determining the costs of the technical measure combination using the energy storage device and the technical measure combination being free of the energy storage device; and evaluating the value of the energy storage device in supporting the distributed photovoltaic power generation system connected to the power distribution network at the determined cost. The accuracy and pertinency of the energy storage application value evaluation can be improved.
Description
technical field [0001] The present invention relates to the field of electric power technology, more specifically, to a data processing-based energy storage application value evaluation method and system. Background technique [0002] With the development of solar energy utilization, the application of distributed photovoltaic power generation systems is becoming more and more popular. Distributed photovoltaic power generation systems refer to distributed power generation systems that use photovoltaic modules to convert solar energy into electrical energy; distributed photovoltaic power generation systems follow local conditions, clean and efficient , decentralized layout, and the principle of nearby utilization, it generally needs to be connected to the distribution network to provide power together with the distribution network; while the distributed photovoltaic power generation system is connected to the distribution network, which often brings some voltage deviation, equ...
