Abstract

The increasing use of distributed generation and energy storage units calls for changing the control methods for distribution grids. It is known that uncoordinated control of multiple "prosumers" (power grid consumers who can also generate power) can lead to unacceptable grid operating conditions. In the present two-part study we present the concept of a unified controller (UC) for prosumers at a 0.4 kV voltage level grids that can prevent the grid entering into undesired operating conditions. In the first part of the study, we present a problem statement with illustrative examples and then proceed to describe the principles of operation of the unified controller (UC). We then describe the laboratory test bench that was assembled specifically to validate the controller performance under real-life conditions. We describe the general arrangement of the test bench and the measurement system required to perform the corresponding controller testing.
