Abstract

In the last 3 years, Vietnam has recorded the booming development of renewable energy as the result of competitive Feed in Tariff price. At the end of 2021, there are 83 wind power plants with the installed capacity of about 4000 MW, which is about 5% of Vietnamese generation capacity. These wind plants are required to have SCADA connection with Vietnam system operator which is EVN National Load Dispatch Center (EVNNLDC). The required SCADA signals are: actual power, circuit breaker status, meteorological data, reactive power, voltage, current. Recently, operation data of every wind turbines is also required to send from wind plants to EVNNLDC via SCADA. As number of signals becomes more as more as recently booming development of renewable energy, it put a big pressure to SCADA system which can be overloaded. In addition, in order to have input for intra-day operation plan, the renewable plants also need to update their forecasting power continuously to web portals. It may be inconvenient as the plant's operator need to enter these values manually as generated power varies throughout the day. To solve these issues, EVNNLDC has deployed a solution to implement signal receiving system via API protocol to increase the data exchange effectiveness from the plants to the dispatch centers. A very large volume of data at resolutions from 5 minutes to 15 minutes without the need of communication via SCADA protocol can be sent - received through this API protocol with many additional features that automatically process information at both the power plant and at EVNNLDC to improve both work performance and accuracy of forecast signals, reduce the load on the SCADA system while ensuring information quality.
