Use of distributed renewable energy resources in the world and Lithuania is growing. It influences because the country’s seeking to reduce CO2 emissions. Electric power generation may be carried out anyone who wants. It is noted that the most popular plants are photovoltaic because of its simple design, no additional land lots, can be installed on buildings. Flexible choice of generated power. Also, simple to operate, it has no mechanical components like wind power. Energy system operators must connect to the system any power generator. Growing number of distributed generators for power system operators brings new challenges to system control. One of the potential opportunity for the integration of distributed generators is formatting virtual power plant from distributed generators. The energy system has never been as it is now. This study accomplished investigation to evaluate the benefits of virtual power plant for integration and development in Lithuania. Investigative work reviews the development dynamics of distributed generators. Also, NORD POOL SPOT electricity trading market, and the legislation of distributed energy resources. The study was accomplished, by simulating virtual power plant of 36 distributed generators – photovoltaic generators. The study volume of the year 2016. Virtual power plant compared with conventional solar power plants. Described virtual power scheduling features. Modeled electricity sales in different scenarios. The investigation showed that the virtual power plant could rise 20% of revenue compared to when electricity would be sold by the average daily or annual price. The integration of distributed generators integration would reduce incentives for the volume to be less burdensome for other electricity consumers. It is also important to mention that the power system operators to date production resources become visible and controlled, mutual benefit. |
