When connected with, quality electricity can be supplied to the grid system in a stable manner. Frequency Regulation A gap between power generation and demand on the grid causes the grid frequency to move away from its nominal value, and this can be regulated using to improve quality of electricity. Deploying can also maximize utilization of coal-fired power plants to reduce power cost. P, Q Control for Distribution Network As renewable energy is being widely adopted, the existing distribution network will reach its full capacity, requiring investment for capacity expansion.
