Why is EMS important?

Moreover, the energy system that employs EMS to predict PV power generation, power outage duration time, etc., enables controlling the start/stop of the DG and in consequence of achieving further fuels savings.

Why is NEC conducting a demonstration test of EMS technology?

NEC is conducting demonstration test of the EMS (en- ergy management system) technology and aims to re- duce both diesel oil consumption and CO2 emissions. Our solution employs an EMS to control the power systems via use of LIB (lithium-ion batteries), PV (photovoltaic) and DG. 2. The Background of the Demonstration Test

Why is a PV system important to utilities?

For example, with the household and industries having own generations, their electricity consumption is no longer predictable by utilities. Therefore, gathering information about the PV system and even controlling the PV systems is of highest importance to utilities.

Are PV systems a challenge to existing grids?

However, with the increasing penetration level, the intermittent and fluctuating energy availability of PV systems are introducing many challenges to existing grids. For example, with the household and industries having own generations, their electricity consumption is no longer predictable by utilities.

Do distributed PV systems need a grid-scale coordinated control network?

The increasing penetration of distributed PV systems also request for a grid-scale coordinated control network. The control paradigm of current electrical power system is slow, open-looped, centralized, human-in-the-loop, deterministic and, in worst-case, preventive.

Why do mobile phone base stations use DGS?

Therefore, many mobile phone base stations use DGs to generate power if the grid power is cut, which consumes over 2 billion liters of diesel oil per year and exhausts over 11 million tons of CO2 per year. In many cases, the mobile phone business in India is shared by several specialist companies.
