Abstract
Rapid prototyping and validation of power system controllers have always been a challenge. With a rapid increase in distributed energy resources (DERs) and power-electronics-based power system devices, the systems that control today’s electrical grid infrastructure are set to become more complex than ever, especially on the distribution front. Thus, rapid prototyping and validation of new complex control systems require testing with extensive set of test cases involving a multitude of power system components. The numerous types of variable involved, such as topology, energy flow, fault conditions, autonomous control systems, and protective device operation, most of which are stochastic in nature, naturally compound the problem of prototyping and validation. In such a scenario, using a hardware-in-loop (HIL) to test all possible test conditions is quite unrealistic. This chapter is about introducing DIgSILENT’s PowerFactory as a good software stand-in for Power Systems in HIL testing.

Notes
- 1.
A brief introduction to OPC technology is given in the next section of this chapter.
- 2.
OPC standards are being maintained by the OPC foundation, and more details can be obtained from the following link: https://opcfoundation.org/.
- 3.
Readers will need to adjust the parameters in “PV Array.ElmDsl” to achieve the desired MW output at a desired voltage.
- 4.
Free version of MatrikonOPC simulation server and server explorer can be downloaded from the following link: https://www.matrikonopc.com/products/opc-desktop-tools/index.aspx.
- 5.
“MatrikonOPC Simulation Server” is freeware and can be downloaded from Matrikon’s Web site. It is recommended that you use all default options for installation.
- 6.
If running on a 64-bit system (x64), the OPC core components from OPC foundation need to be installed in addition. They are not required for 32-bit systems. These components can be downloaded from the OPC foundation Web site for free.
- 7.
This is the program location if the server was installed accepting all default options. If not, start the server from the custom location.
- 8.
OPC OSE is not discussed in this chapter. Contact DIgSILENT for their OPC OSE example.
- 9.
Refer to the PowerFactory user manual for more details about configuration parameters in the initialization screen.
