The severity of these issues depends on the penetration level of PV, configuration of distribution system and the location of PV in distribution system. In such cases, high level of PV penetration can inject power to transmission network which can affect the voltage level and protection setting of the distribution system.
Normally, the solar energy grid con- Table 2. Range of voltage at the PCC. c. If the frequency is 50.2 Hz, the solar power plant shall inject active power up to 51.5 Hz. operator and the owner of solar power plant. not exceed 10% (of the rated active power of the plant) per minute. quality of the voltage waveform at the PCC.
Voltage quality can be affected by the intermittency of PV power output in distribution system . Generally, for PV generation type, climate changes can create irradiance fluctuations either for a short or long period of time. Therefore, this can affect the voltage output of PV in Point of Common Coupling (PCC).
The voltage problem of distribution system that has been connected with PV can be characterized as voltage rise, voltage unbalance and flickers in the network. 4.2. Voltage rise
The impact of these has to be carefully analyzed and mitigated in order to prevent these issues from jeopardizing the grid and the power quality in the system. The main issues in the solar penetration in distribution system are voltage related issues, harmonics and islanding detection.
Some major standards for PV integration in distribution systems such as IEC 61727, IEEE 1547, and VDE-AR-N4105 are defined and used in to ensure that the power quality and stability defined by grid codes for PV sources connected to the grid are maintained.
