6 FAQs about [Reverse Flow Solar Power Generation]

What is reverse power flow?

A reversal of the traditional power flow from distribution to transmission system by too much DER penetration is referred as ‘reverse power’ flow in this paper and the interconnecting transformers are of special interest.

What happens if you reverse power flow in a low-voltage network?

Reverse power flow in a low-voltage (LV) network can cause instability, such as in the line sections and distribution transformers [19, 20]. The overloading of the distribution transformer is one consequence of a low-load, high-PV penetration network; higher voltages are also seen at low-voltage (LV) and medium-voltage (MV) levels. [21, 22].

How does reverse power flow affect Transformer life?

If the reverse power flow is not restricted, then interconnect transformer losses its life by 25%. The restriction on power factor of reverse power flow can maintain the life of transformer. The amount of impact on transformer life depends on design of the transformer and operating conditions.

Does reverse power flow affect radial network transformer loadings?

A simulation model of a real urban electricity company in Ghana is investigated against various PV penetration levels by load flows with ETAP software. The impact of reverse power flow on the radial network transformer loadings is examined for high PV penetrations. Using the least squares method, simulation results are modelled in Excel software.

How does reverse power flow affect Protection coordination scheme?

The reverse power flow occurs when the production of DG exceeds local load demand or when local demand reduces so that power flows in the opposite direction and causes abnormal performance of the protection system. In this section, the effect of reverse power flow on the protection coordination scheme is analysed.

What are the effects of a short-circuit & reverse power flow?

Due to the increase in short-circuit level and reverse power flows, the main impact on protection system is relay desensitization, unintentional islanding, blinding of protection, line to ground over-voltage on utility side and miscoordination of protective devices .
