LOAD-SHARING HYBRID SYSTEMS
Solar Energy - a look at load-sharing hybrid systems
The rapidly increasing demand for energy in developing countries is creating a large and growing market for off-grid power systems. The electrification of rural or remote areas within these countries is problematic as many do not have the infrastructure to supply grid energy and investment into developing their networks does nothing to solve the immediate demand. It is often found to be cost-prohibitive anyway, with some countries having additional challenges to consider. The experts from DSE reflect on the issues.
becoming a popular solution. Other countries are also switching on to the benefits of utilising PV in hybrid systems to help meet government green energy initiatives. Looking to the future and the upward trend

implications of load sharing two totally different power sources and learn how to simplify the merging technologies. This feature identifies areas formerly thought to be problematic or complicated, and demystifies the subject using proven techniques and smart new age technology from DSE. We also take a look at how to maintain minimum fuel consumption from the genset and maximum utilisation of the renew- able energy to meet modern energy targets.

user-friendly control solution which helps to simplify system design and removes many of the myths and barriers to operating within the hybrid market. There is no reason why renewable energy
inverters cannot be paralleled with generator(s) in exactly the same way as they would parallel with the grid supply, however there are a few key points that must be considered. Using a suitable genset control module
from the DSEGenset range offers all the usual sophisticated functionality associated with the product but until recently linking this to an inverter based system, while possible, has been complex. Now the alternative easy solution is to use
The DSEM870 complies with Sunspec modbus inverter protocols and is capable of communicating with multiple DSE Genset control modules and multiple inverters in any one system.
a DSEM870 which has the ability to communicate with the DSE genset control module and the inverter and, depending on the information received, will regulate the inverter output accordingly.
Setting the inverter to fixed export
The inverter would be set for fixed export up to the appropriate maximum level, with the generator(s) set in Frequency Control mode to automatically provide the remainder of the
