CEMS makes the optimized plan for

supply and demand of electric power,

heat and gas (hydrogen).

In case of supply-demand imbalance,

supply-demand adjustment or

demand response will be

implemented via each EMS.

New energy systems (solar and wind power) are not stable.

Variation in electric power generated by the new energy systems cause the supply and demand imbalance.

Demand for new energy is increasing significantly. A reverse power flow poses the voltage rise problem.

CEMS plays a key role in solving these problems.

◆Key features- Prediction of power generated by new energy

(PV and Wind Turbine Generator)

- Optimized planning and control of supply and demand, and

frequency control by utilization of storage batteries.

- Demand response service for balancing the load

- Smart meters for consumers

CEMS (Community Energy Management System)

15

◆Extendibility- Multi-languages

(Japanese, English and Chinese)

- Control several regions by a single system

- All in one package

◆ Role of smart PCS

Smart PCS plays a key role in controlling fluctuation of frequency and voltage caused by increased electric power generation

by renewable energy

◆ Advantageous functions

● Communicating with EMS, stabilizing loads by two-way

communication and providing reserved capacity in an emergency

● Reducing instantaneous frequency variations by high-speed

frequency control

● Governor-free function

● Controlling voltage by reactive power

● Stand-alone operation with variable frequency control

Power-conditioningsystem

Smart Meters for Demand Response

17

◆ Advantageous functions

● Wireless bilateral communication with the home display

● DR and DP information on the home display

● Customers can see watt-hours usage, which will prompt them to

save energy.

● 30-minute watt-hours and data for 44 days

● Controlling electric power supply in an emergency

● Amendment of electric power contract by service breaker

function

◆ Role of smart meter

With the smart meter, CEMS performs automated meter reading. In order to stabilize loads and balance supply and demand, the smart

meter provides CEMS's request for demand response, and also shows watt-hour usage.
