Renewable Energy Projects
Renewable energy power generation is constantly growing as a result of promotional policies and development of renewable energy harvesting technologies.
Intermittent generation of renewable energy power plants can cause power quality problems and other challenges that must be coped for the successful system integration. With EA-PSM Electric it is possible to solve technical or general type problems related to renewable energy power plants integration and design.

Solar PV energy calculation
Solar PV daily, monthly and annual power generation estimation is necessary to calculate the payback period of the installation.
Choose peak-power modules, select optimal AC & DC cables as well as inverters.
EA-PSM allows to calculate solar PV system power generation. This calculation module is based on the parameters of PV modules and inverters, solar power plant geographical location, modules positioning.
DC Network Design
Proper DC network modeling requires to perform calculations of short circuits and normal mode currents. These calculations are necessary for selecting cables as well as protection equipment.
EA-PSM allows to calculate DC network with solar PV arrays.
This module will evaluate solar PV and inverter models, also solar irradiation. Software has a broad library of over 13000 PV modules and 4600 inverters.
Wind turbine power quality assessment
The flicker as a result of wind turbines has gained attention in recent years. Rapid variations in wind speed produce fluctuating power, which can lead to voltage fluctuations at the point of common coupling (PCC), which in turn generate flicker.
EA-PSM allows to calculate voltage flicker due to continuous operation, due to switching operation (start-up at cut-in wind speed, start-up at rated wind speed or higher, worst case switching between generators) and relative voltage change due to a switching operation.
