4. Solar energy integration:
Vietnam Electricity
(i) Solar master plan: Solar development have to comply with the revised
master plant 7th, comply with the target of the government related to
solar development plan.
(ii) Grid code and Distribution code should be reviewed and revised as the
case may be, in order to reflect of solar integration.
(iii) System study should be implemented in order to optimize the auxiliary
services with the more and more penetration ratio of solar and other
intermitted energy.
