To address the problem of combined heat and power economic emission dispatch (CHPEED), a two-stage approach is proposed by combining multi-objective optimization (MOO) with integrated decision making (IDM). First, a practical CHPEED model is built by taking into account power transmission losses and the valve-point loading effects. To solve this model, a two-stage methodology is thereafter proposed.The first stage of this approach relies on the use of a powerful multi-objective evolutionary algorithm, called θ-dominance based evolutionary algorithm (θ-DEA), to find multiple Pareto-optimal solutions of the model. Through fuzzy c-means (FCM) clustering, the second stage separates the obtained Pareto-optimal solutions into different clusters and thereupon identifies the best compromise solutions (BCSs) by assessing the relative projections of the solutions belonging to the same cluster using grey relation projection (GRP). The novelty of this work is in the incorporation of an IDM technique FCM-GRP into CHPEED to automatically determine the BCSs that represent decision makers' different, even conflicting, preferences. The simulation results on three test cases with varied complexity levels verify the effectiveness and superiority of the proposed approach.

“…Also, it is difficult to dispatch CHP plants according to marginal power production costs that depend on heat generation level. Recently, [19] proposed a generic solution approach for the multi-site CHP system based on the decomposition framework, where the marginal power production costs of a single-site CHP system are computed according to parametric analysis [20]. Due to inherent inefficiency of parametric analysis, this approach is difficult to apply to a large system with a moderate planning horizon.…”

This paper deals with the transmission-constrained multi-site combined heat and power (CHP) problem and formulates it as a linear programming (LP) model with a special structure. CHP systems are treated as an extension of power-only systems. Each site can be treated as a regional energy system to supply both heat and power. Heat demand is satisfied by local production while power demand can be satisfied by local generation plus power exchange over the power network. The challenge of this problem is that power transmission needs to be coordinated with both power and heat production in each site.The transmission-constrained multi-site CHP system can be operated cost-efficiently according to hourly demand forecast for heat and power by coordinating production and transmission activities among different sites. An efficient network power Simplex algorithm is developed to this end.Numerical experiments with realistic test data show that the algorithm is 7 to 360 (with average 30) times faster than a commercial LP code.

“…This new form of energy supply has the following new characteristics: (i) structure features: power grid topology has more complex structure types (tree or mesh), flow types (unidirectional or bidirectional) and energy consumption programs (on demand or dynamic balance); (ii) environmental characteristics: most distributed energy have characteristics of instability (solar energy, wind energy and tide are influenced by environmental factors); (iii) functional features: plug and play puts forward higher requirements for the power quality management ability as dynamic change exists in both sources and loads. So stability and reliability would be of paramount importance for the coming form of power supply system [2][3][4][5]. For instance, due to the intermittent nature of the PV energy sources or wind turbine sources, considerable complexity and variability are introduced into the micro grid [6][7][8].…”

Power quality issues have become one of the most important issue for researchers to concern. In this paper, simulation and experiment of algorithm and circuit design of Unified Power Quality Conditioner (UPQC) are provided. Control algorithm and topology design of one UPQC which includes active power filter (APF) and dynamic voltage restorer (DVR) are introduced. Stability condition of the filter unit is deduced and proved by Routh stability criterion. Simulation for APF and DVR is carried out in PSCAD to show the proposed control strategy. Experiments such as current tracking, harmonic detection and compensation and voltage drop compensation are provided in details. Experimental results show that the proposed control method and the designed topology are effective and practical.
