With China’s “Emission peak, Carbon neutrality” strategic goal, the traditional energy industry will usher in new challenges and development opportunities. Photovoltaic, wind power, stored energy and other new energy sources will have better development space in the future. SmartGen has deeply engaged in the field of genset control for many years, combined with the characteristics of hybrid energy and unique advantages in genset control, developed the hybrid energy control system with HES9510 as the core.
Hybrid energy includes solar energy, stored energy, wind energy, mains, and genset. HES9510 is used for genset and energy system like solar energy, wind energy, energy storage battery with inverter as output, which can control start/stop of inverted power, output mode, output size and output breaker close/open, etc. It can also control genset start/stop according to the load condition, provide spinning reserve for inverted power, and control converter to charge and discharge the energy storage battery, thus realizing data measurement, alarm protection and “three remote” (remote control, remote measurement, remote communication) functions. The mains application scenarios are as following：
Resort Hotel
It is mainly supplied by mains, solar energy and genset. Under normal conditions, solar energy and mains are grid-connected to supply power, which can realize peak-valley TOU tariff scheduling mains and solar energy supply. When mains becomes abnormal, the optimal configuration of supply can be realized by solar energy paralleling with genset.
Island
It is applied to remote island without mains. The system is composed by wind energy, solar energy (PV), storage energy battery pack and genset. Wind and solar energy supply the load and charge the energy storage battery pack during the day, wind and energy storage battery pack take load in the evening, if the battery pack lacks power, genset will take load.
Industry
The supply energy is composed by mains, solar energy, stored energy, wind energy and genset. Combined with our actual application of hybrid energy supply system, the following is an introduction to the functions and system running of HES9510.
1) System Composition
2) Running Description
Solar energy and stored energy grid-connection supplies power for the industry from 8:00am; The stored energy is insufficient to withdraw from the supply system, solar energy grid-connection begins to supply power. Mains charges the energy storage battery from 12:00pm to 8:00am the next day to realize economic deployment of peak-valley TOU tariff. Solar energy can be used to generate about 20kWh of power per day.HES9510 controller can communicate with inverter, converter, BMS via RS485 interface, and schedule the utilization of energy. It can communicate with multi-unit parallel controller HGM9510N and bus grid-connection controller HGM9560 via MSC to realize hybrid supply control of mains, generator, stored energy, photovoltaic and wind power system. Our developed 15.6-inch color touch screen display can remotely monitor the overall system running and monitor on phone or PC via “Cloud Monitoring” platform.
HES9510 Application Modes:
1.With Mains (Large Power Grid): Power is adjusted through HGM9560. Constant active power and reactive power is outputted to mains according to the set energy priority. VF is provided by bus while PQ is provided by other energies.
2.Island Mode (Micro-grid): Mains is unavailable. The unit will take load according to the set energy priority (exclude mains). VF is provided by genset prior to energy storage power station. PV power station can’t take load alone.
3.Active Control Mode
Constant power mode: It constantly outputs set active power.
Inverter control mode: The output of active power is controlled by inverter itself but not controller.
4.Reactive Control Mode
Constant power mode: It constantly outputs set reactive power.
Power factor control mode: Reactive power outputs according to power factor, or controller automatically controls the inverter according to power factor (if inverter supports).
