“…The problem considered in this paper was dealt with in literature almost always from the point of view of traditional generation companies (GENCOs), using sequential models [16,17,18,19,20,21] or joint model [13,14,15,22,23,24,25,30].…”

The paper is addressed to the construction of an optimally bidding for a Micro Grid (MG) that takes part to both day-ahead energy and spinning reserve markets. The work shows that the decision about the amount of power to offer, related to the expected prices and different risk tolerances, must be taken contextually through a joint approach. For that purpose, an optimization problem is formulated. In order to help the decision maker to understand the potential impact of different sub-optimal choices, the model evaluates also the risk associated with the uncertainty of variable power to offer in the both markets. The risk associated is evaluated by the expected utility theory that takes into account the attitude of individuals with regard to risk (adversion, neutrality or propensity) to make decision that minimize negative returns. The effectiveness of the proposed model is assessed through the analysis of a MG composed by traditional power plants, combined heat and power (CHP) plants, and heat production plants (boilers). The presence of storages systems is also accounted for. Moreover, it is considered that both generators and loads can take part in the reserve market and the demand participation happens through both shiftable and curtailable loads.

The active distribution network (ADN) is able to manage distributed generators (DGs), active loads and storage facilities actively. It is also capable of purchasing electricity from main grid and providing ancillary services through a flexible dispatching mode. A competitive market environment is beneficial for the exploration of ADN's activeness in optimizing dispatch and bidding strategy. In a bilateral electricity market, the decision variables such as bid volume and price can influence the market clearing price (MCP). The MCP can also have impacts on the dispatch strategy of ADN at the same time. This paper proposes a bilevel coordinate dispatch model with fully consideration of the information interaction between main grid and ADN. Simulation results on a typical ADN validate the feasibility of the proposed method. A balanced proportion between energy market and ancillary services market can be achieved.

“…[1] However, there are many different terms, definitions, and rules concerning what operating reserves entail. In general, operating reserves are classified into three categories, regulation, spinning, and non-spinning reserves.…”

“…The practical experience may set operating reserve requirement by establishing that the amount of generation reserve available should be at least greater than or equal to the largest generation unit committed and should be no less than a certain percentage of total operating capacity. [1] As a result, the existing rule for determining reserve requirements does not consider technical and economic aspects. In addition, this approach is also not suitable in terms of power system reliability when the large load fluctuation occurs.…”

“…Most of researches determine the amount of operating reserves capacity by considering the loss of largest generator and a certain percentage of the peak load. [1] For example, Union for the Coordination of Transmission of Electricity (UCTE) merely recommends that the sum of secondary and tertiary control reserves that is operating reserves should cover the largest loss of supply. Moreover, in the areas of UCTE, the required amount of primary control reserves is clearly calculated, however the rule for determining secondary and tertiary control reserves capacity is not precisely specified.…”

-Determination of the required reserve capacity has an important function in operation of power system and it is calculated based on the largest loss of supply. However, conventional method cannot be applied in future power system, because potential grid-connected distributed generator and abnormal temperature cause the large load imbalance. Therefore this paper address new framework for determining the optimal required reserve capacity taking into account the real time load imbalance. At first, we introduce the way of operating reserve resources which are the secondary, tertiary, Direct Load Control (DLC) and Load shedding reserves to make up the load imbalance. Then, the formulated problem can be solved by the Probabilistic Dynamic Programming (PDP) method. In case study, we divide two cases for comparing the cost function between the conventional method and the proposed method.
