Abstract [en]

Renewable distributed generation such as wind power and photovoltaics are gaining popularity all over the world. The overall aim of this Master thesis was to gather experience and knowledge regarding small wind power and photovoltaic with both a market based evaluation and technical description. Methods used have been literature review, interviews with market participants, evaluation of a wind mill and a photovoltaic system simulation with PVsyst 5.41.

It was found that the main common incentive today for the development and spread of small wind power and photovoltaics for market participants is the symbolic value. It was also discovered that the market situation is complicated for the producing consumer.

The spread of small wind power and PV today are a few per mille of a future potential, where politics largely control development and spread of small-scale solutions. The market is unclear and solutions around net charge is still an ongoing debate. Majority of the interviewed persons believes more in PV than in small wind power due to facts such as wind power is size-dependent and not optimal to build in urban areas.

Results show that power quality issues are dependent on the network system as a whole and are often a matter of cost and can be prevented with different technical solutions. One conclusion was that bidirectional power flow increase complexity of problems around protection. Major energy companies are involved in projects to gather knowledge how to deal with DG both in technical aspects and how to deal with customers practically.
