The methodology for the study is briefly shown in Figure 3-1. In this study, Vietnam's power transmission system (500-220kV) will be simulated in peak/off-peak load conditions with the largest proportion of renewable energy sources (lowest system inertia).
However, in Vietnam, there is a widely held industry perception that Battery Energy Storage Systems (BESS) are not economically feasible at this moment, while the country's first pumped storage hydropower (PSH) project Bac Ai with a capacity of 1,200 MW will not be commissioned until 20289.
(i)Current status of Vietnam's power system with high RE (solar and wind power) rate, and the capacity of RE projects is greatly fluctuated. (ii) Advantages and disadvantages of operating a power system with a high RE rate. (iii) Demand and necessity of electricity storage in the current and future power system of Vietnam.
If all generating units in the system are considered, the total inertia of Vietnam’s power system in 2022 is about 1.785s. By 2030, the proportion of renewable energy in Vietnam’s power system is expected to increase to about 30%, the total inertia of the system will be reduced to 1.777s.
According to PDP 8, by 2030, a generating unit of O Mon thermal power plant will be the largest conventional generating unit in Vietnam’s power system with the capacity of 1050 MW. The contingency in that unit is simulated at 5 s after the normal steady state operation.
The simulation is performed by using data from Vietnam’s power transmission system (500 – 220 kV) in 2030 according to the PDP 8. The following operation modes are considered in the simulation: Day time peak load- The proportion of renewable energy proportion is about 21.4%.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide.
