3. In residential installations the domestic circuits and the solar inverters are usually connected to the grid at one common point The installation becomes part of the low voltage LV distribution system Commercial installations are normally larger and therefore connected to the medium voltage MV system Large scale commercial systems such as power plants can be connected to the high voltage HV grid Each of the power systems has individual ancillary service requirements Depending on the location and the DNO some of these services will be mandatory and others are optional Mandatory requirements are automatically configured through the selected grid code Optional services are configured by the installer during commis sioning Grid support can be divided into the following main groups which will be covered in subsequent sections e Dynamic Network Support Active Power Control e Reactive Power Control 9 1 1 Active Reactive Power Theory The principle in generating reactive power is that the phases between the voltage and the current are shifted in a controlled way Reactive power cannot transport consumable energy but it generates losses in power lines and transformers and is normally unwanted Reactive loads can be either capacitive or inductive in nature depending on the current leads or lags in relation to the voltage Utility companies have an interest in controlling reactive power in their grids for e

11. The total length is defined as twice the physical distance between the inverter and the PV array plus the length of the PV cables included in the modules Avoid looping the DC cables as they can act as an antenna of radio noise emitted by the inverter Cables with positive and negative polarity should be placed side by side with as little space between them as possible This also lowers the induced voltage in case of lightning and reduces the risk of damage DC Max 1000 V 12 A Cable length 4 mm 4 8 Q km Cable length 6 mm 3 4 Q km gt 200 300 m Table 4 16 Cable Specifications The distance between inverter and PV array and back plus the cumulative length of PV array cabling 4 3 1 Recommendations and Goals when Dimensioning Optimising the PV Configuration Voltage The output power from the inverter can be optimised by applying the maximum open circuit input voltage Vacmax per input The minimum limit for open circuit voltage is 500 V Examples 1 In a PV system of 75 modules each with an open circuit voltage of 40 V at 10 C and 1000 W m it is possible to connect up to 25 modules in one string 25 40 V 1000 V This allows for three strings and every string reaches the maximum inverter input voltage of 1000 V at 10 C and 1000 W m2 similar to PV system examples 1 and 2 2 Another PV system only has 70 modules of the same type as above Thus only two strings can reach the optimum of 1000 V
