Description

Technical Field

[0001] This invention belongs to the field of power optimization control technology, specifically relating to an integrated optimization control system for power terminal distribution substations. Background Technology

[0002] Currently, the large-scale integration of distributed interactive devices into distribution networks has made them a significant participant in the new distribution network, while also bringing more uncertainty and randomness to the distribution system. The emergence of new participants necessitates a shift in power dispatch from the traditional "source follows load" model to a highly integrated "source-grid-load-storage" model. However, the actual situation of distribution networks is characterized by wide coverage, diverse specialties, and significant differences in infrastructure. How to construct a distribution network that can adapt to the large-scale integration of distributed interactive devices is an area that power grid companies urgently need to explore. In particular, for distribution substations, the integration of new loads such as distributed photovoltaic (PV) power and electric vehicle charging piles has brought many problems to the substations. Due to the mismatch between the spatiotemporal characteristics of PV power generation and electricity load, PV power is transmitted in large quantities during certain periods, causing reverse power flow. At this time, the grid equipment may experience reverse power transmission, or even reverse power transmission leading to equipment and line overload, seriously affecting the safe operation of the grid. Therefore, it is necessary to develop an integrated optimization control system for power terminal distribution substations that is easy to operate, use, and efficient to solve the distribution aggregation and coordinated control of substations with distributed PV, charging piles, energy storage systems, and controllable loads. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a convenient, efficient, and rationally designed integrated optimization control system for power terminal distribution substations.

[0004] The objective of this invention is achieved as follows: an integrated optimization control system for power terminal distribution substations, comprising a data acquisition component, a data processing module, a data integration and transmission module, an intelligent analysis module, and a control and operation module. The data acquisition component is used to acquire the operating status, topology parameters, and renewable energy regulation performance information of each device within the distribution substation, while also acquiring the control information of the devices within the low-voltage distribution substation at the previous moment. Specifically, the data acquisition component comprises multiple low-voltage intelligent monitoring devices, which are distributed and installed at each distribution box, branch box, and meter box within the distribution substation. The data processing module is used to filter and process data information. It is installed inside the data acquisition component and consists of a filtering unit and a pre-analysis processing unit. The filtering unit can filter the data to remove abnormal data and error information generated during the transition state when the operating mode changes. The pre-analysis processing unit can perform noise reduction, integration registration and structuring processing on the data information to increase the compactness and density of the data while reducing the amount of data transmission. The data integration and transmission module is used to integrate the data after filtering and preprocessing by the data processing module, form data packets, and transmit the data packets in real time. The intelligent analysis module is used for analyzing and processing data packets. It has a modeling component and an analysis unit. Using the modeling component, through digital twin technology, virtual digital human, 3D GIS technology, 5G communication technology, digital twin semantic map, and cloud computing edge computing technology, and applying virtual reality and 3D map technology, it performs 3D reconstruction of the equipment distribution in the distribution area to form a 3D visualization image. Then, the analysis unit analyzes and processes the operating status and control information of the equipment in the distribution area, marks abnormal operating status and unreasonable control adjustment, and generates an optimized adjustment plan. The control and operation module is used to control and adjust the equipment. It can also manually review the optimization and adjustment scheme generated by the intelligent analysis module. After the manual review is successful, the optimization and adjustment scheme is executed through the internal execution unit.

[0005] Furthermore, the data integration and transmission module is internally equipped with a marking unit and a storage unit. The marking unit can mark and annotate the data packets collected by different data acquisition components, and the storage unit can store and back up the transmitted data packet information.

[0006] Furthermore, the data integration and transmission module is equipped with a wireless transmission unit, which is used to realize the wireless transmission of data packets.

[0007] Furthermore, the intelligent analysis module is equipped with an intelligent optimization module, which can be used to quickly generate optimization and adjustment schemes.

[0008] Furthermore, the data acquisition component is equipped with a positioning unit, which can be used to mark the location of the acquired data information.

[0009] The beneficial effects of this invention are as follows: This invention, by setting up a data acquisition component, acquires the operating status, topology parameters, renewable energy regulation performance information, and control information of the equipment within the distribution substation at the previous moment for each device. Simultaneously, by setting up a positioning unit within the data acquisition component, the location of the acquired data can be marked. By setting up a data processing module and a data integration and transmission module, the data processing module can perform filtering and processing operations on the data. Specifically, the filtering operation removes abnormal data and error information generated during transitions when the operating mode changes. The processing operation performs noise reduction, integration registration, and structuring on the data, increasing the compactness and density of the data while reducing the amount of data transmitted. The data integration and transmission module can be used to integrate data, forming data packets and transmitting them in real time. By setting up an intelligent analysis module, data packets can be analyzed and processed. This module includes modeling components and analysis units. Using the modeling components, digital twin technology, virtual digital humans, 3D GIS technology, 5G communication technology, digital twin semantic maps, and cloud computing edge computing technology, along with virtual reality and 3D mapping technology, the distribution of equipment within the distribution area can be reconstructed in 3D, forming a 3D visualized image. The analysis units can analyze and process the operating status and control information of the equipment within the distribution area, marking abnormal operating states and unreasonable control adjustments, while generating optimized adjustment schemes. A control and operation module allows for the control and adjustment of equipment, and also enables manual review of the optimized adjustment schemes generated by the intelligent analysis module. Overall, this invention has the advantages of being convenient, efficient, and rationally designed. Attached Figure Description
