Abstract:
Renewable energy sources (RES) can provide valuable flexibility potential for multiple markets and grid services in the future. In this paper, the focus lies on the development of algorithms for an optimal dispatch and bidding of a RES-based virtual power plant (VPP) by considering current short-term and balancing market conditions in Austria, as well as a proposed redispatch market. Specifically, different pricing and bidding strategies for a redispatch market are compared and their feasibility is analyzed. The attractiveness of different pricing models and remuneration mechanisms for redispatch, as well as the influence of the redispatch call probability on the bidding behavior of the VPP, is investigated. The simulation of the bidding behavior is carried out using linear optimization techniques. The paper describes the algorithms as well as the assumptions for market rules in redispatch, balancing and short-term electricity markets. The results show that the probability to be activated for redispatch and thus the required incentives depend highly on the location of the plant. Pre-curtailment of the plant to offer positive redispatch is not recommended as the prices would need to be set at up to 200–300% of the day-ahead price.

Abstract:
In light of the necessity for a cost-effective transition to a new energy system, it has become increasingly important to consider the integration of redispatch measures as a potential option in long-term grid planning. This could help to avoid the need for significant expansion of the grid and storage facilities. In this paper, we present a novel method for the consecutive optimization of the sector-coupled electricity system of the year 2035 at bidding zone level, as well as on a 300 bus model of the German extra high and high voltage grid. Therefore, redispatch can be explicitly co-optimized in conjunction with grid and storage expansion. The results demonstrate that redispatch measures can markedly reduce the necessity for grid and storage expansion, ranging from 76% to 78% in the German grid. By employing only 21% of the optimal annual redispatch volume, 77% of the potential investment cost savings can already be captured.

Abstract:
Mit dem Netzausbau-Beschleunigungsgesetz 2.0 nimmt der Gesetzgeber Akteure der Energiewirtschaft in die Pflicht, kleinere Erzeugungsanlagen in das Management von Netzstabilität und Engpass-Vermeidung einzubeziehen. Das heißt im Klartext: Der Redispatch-Prozess wird komplexer und kleinteiliger. Speziell Anschluss- und Verteilnetzbetreiber als auch Anlagenbetreiber sind gefordert, ihre Systeme für die kommenden Aufgaben fit zu machen. Anlass genug, sich mit dem Konzept „Virtual Power Plant“ als Anlagenleitsystem intensiv zu befassen. Umso mehr, da es den Boden für zusätzliche wertvolle Service-Aktivitäten im Energiemarkt ebnet.

Abstract:
Risk-based redispatch optimization is proposed as a methodology to support the Transmission System Operator (TSO) with preventive remedial actions obtained by extending the security-constrained unit commitment/economic dispatch with constraints resulting from the risk assessed for the power system. Although being heuristic, the methodology is based on comprehensive dynamic security assessment as time-domain simulations are used, allowing to express the degree of all types of instabilities, e.g., caused by contingencies, in monetary terms. Therefore, the risk is assessed as the expected value of the cost incurred by the TSO. Such an approach forms a new pathway to including risk in planning procedures already used by TSOs. Results obtained for the IEEE39 dynamic power system, with costs assigned to load shedding and generator tripping due to single transmission lines short-circuits, are shown as a reference case.

Abstract:
Zusammenfassung Die Optimierung von Engpassmanagementmaßnahmen ist ein bedeutender Forschungsschwerpunkt in der elektrischen Energieversorgung. Hierfür haben sich unterschiedlichste Methoden etabliert. Diese Methoden verwenden sowohl klassische als auch heuristische Optimierungsalgorithmen, um das Engpassmanagementproblem zu lösen. Der Fokus dieser Veröffentlichung liegt auf der Darstellung aller Schritte, die zur Linearisierung des Engpassmanagementproblems notwendig sind. Darauf aufbauend wird ein gemischt ganzzahliges lineares Optimierungsproblem aufgebaut, das sowohl die Kraftwerkseinsatzplanung als auch das Engpassmanagement umfasst. Die entwickelten Optimierungsalgorithmen werden auf ein Testszenario basierend auf dem IEEE 24 Knoten Netz angewandt. Mit Hilfe des vorgestellten Algorithmus ist es möglich, das Netz engpassfrei zu betreiben. Zum Ausgleich des Linearisierungsfehlers muss der Algorithmus auf das Beispielnetz dreimal angewandt werden.

Abstract:
Modern electrical power systems integrate renewable generation, with solar generation being one of the pioneers worldwide. In Latin America, the greatest potential and development of solar generation is found in Chile through the National Electric System. However, its energy matrix faces a crisis of drought and reduction of emissions that limits hydroelectric generation and involves the definitive withdrawal of coal generation. The dispatch of these plants is carried out by the system operator, who uses a simplified mechanism, called “economic merit list” and which does not reflect the real costs of the plants to the damage of the operating and marginal cost of the system. This inefficient dispatch scheme fails to optimize the availability of stored gas and its use over time. Therefore, a real-time redispatch model is proposed that minimizes the operation cost function of the power plants, integrating the variable generation cost as a polynomial function of the net specific fuel consumption, adding gas volume stock restrictions and water reservoirs. In addition, the redispatch model uses an innovative “maximum dispatch power” restriction, which depends on the demand associated with the automatic load disconnection scheme due to low frequency. Finally, by testing real simulation cases, the redispatch model manages to optimize the operation and dispatch costs of power plants, allowing the technical barriers of the market to be broken down with the aim of integrating ancillary services in the short term, using the power reserves in primary (PFC), secondary (SCF), and tertiary (TCF) frequency control.

Abstract:
Electricity grids require the ancillary services frequency control, grid operation, re-establishment of supply and voltage stability for a proper operation. Historically, conventional power plants in the transmission grid were the main source providing these services. An increasing share of decentralized renewable energy in the electricity mix causes decreasing dispatch times for conventional power plants and may consequently lead to a partial replacement of these technologies. Decentralized energy sources are technically capable of providing ancillary services. This work focuses on the provision of reactive power for voltage stability from decentralized sources. The aim is to answer the question of how voltage stability and reactive power management can be achieved in a future electricity system with increasing shares of decentralized renewable energy sources in an economical and efficient way. A methodology that takes reactive power and voltage stability in an electricity system into account is developed. It allows for the evaluation of the economic benefits of different reactive power supply options. A non-linear and a linearized techno-economic grid model are formulated for this purpose. The analysis reveals an increasing importance of reactive power from the distribution grid in future development scenarios, in particular if delays in grid extension are taken into account. The bottom-up assessment indicates a savings potential of up to 40 mio. EUR per year if reactive power sources in the distribution grid provide reactive power in a controlled manner. Although these savings constitute only a small portion of the total cost of the electricity system, reactive power from decentralized energy sources contributes to the change towards a system based on renewable energy sources. A comparison of different reactive power remuneration mechanisms shows that a variety of approaches exist that could replace the inflexible mechanisms of obligatory provision and penalized consumption of reactive power that are mostly in place nowadays.
