Sažetak
The most distinguished global trend in power systems development in the last decade is by far rapid growth of power generating facilities driven by renewable energy resources. In theory, their primary energy source is a free natural resource such as wind or solar radiation, therefore, their integration should lead to lower marginal costs at wholesale level and therefore lower retail electricity prices payed by end-consumers. The problem lies in their non-dispatchable and stochastic nature. Inability to be dispatched in accordance to power system real-time conditions means that they cannot be committed in the time of need for the power system, i.e., they are unable to provide balancing reserves. Stochasticity of their generation leads to greater need for flexible units capable of changing their operating point, i.e. the greater need for operating reserve units. One can conclude, when the share of renewable energy sources increases, the share of units capable of operating reserves provision decreases, but at the same time the operating reserve requirements increase. Possibilities to solve mentioned problem and to bolster further renewable energy sources integration range from integration of a new flexible conventional units (such as gas power plants), or an energy storage technologies, to usage of renewable units for operating reserves provision despite their lost opportunity cost occurrence. When observing operating reserve’s adequacy, it is very important to evaluate the way how it is allocated. With efficient reserve allocation method, the need for additional investments in power system flexibility are deferred and mitigated. This paper provides an insight into different ways of reserve allocation and how does it affect total operating costs of the power system.
